Polymers have for very long been a fundamental piece of our everyday lives so much so that examples can be found almost ubiquitously. We have an effect that leads us to trust that polymers are only plastics useful for packaging, in household objects as well as for making fibres, however this is the tip of the iceberg.

Polymers are utilized in many applications you may not have thought much about. This blog enlightens you concerning the story behind polymers and the way it’s evolved since that time to serve several functions across numerous industries.
Origin of polymer science
Humans have taken benefit of the versatility of polymers for years and years by means of oils, tars, resins and gums. However, it had not been before the industrial revolution that the polymer industry started to realize. In fact, the birth of polymer science might be traced returning to the mid-nineteenth century. In the 1830s, Charles Goodyear developed the vulcanization procedure that transformed the sticky latex of natural rubber in to a useful elastomer for tire use. In 1909, Leo Hendrik Baekeland designed a resin from two very common chemicals, phenol and formaldehyde. The reaction between these two chemicals led the way to add mass to a resin, called Bakelite, named after him. It was this resin that served as being a harbinger to many people of the common polymers we use today. The word “polymer” comes from the Greek roots “poly” and “mer,” which build means “many parts.” Polymeric substances are composed of several chemical units called monomers, that happen to be gathered into large molecular chains consisting of a large number of atoms.
Classification of polymers
On the basis of their origin, pmma plastic can be considered synthetic or natural polymers. Natural polymers are the types polymers that exist in nature knowning that that happen to be isolated from plant and animal resources. Starch, cellulose, proteins, natural rubber etc. are a couple of examples of natural polymers. Though these are processed to find the end product, because the basic material develops from a natural source, these polymers are referred to as natural polymers. Natural rubber originating from tree latex it’s essentially a polymer produced from isoprene units with a tiny proportion of impurities inside it.
Within this context, biopolymers may also be significant. There is vast number of biopolymers for example polysaccharides, polyesters, and polyamides. These are naturally made by microorganisms. The genetic manipulation of microorganisms makes method for enormous prospect of the biotechnological manufacture of biopolymers with tailored properties well suited for high-value medical application for example tissue engineering and drug delivery.
Synthetic polymers, as their name indicates, are synthesized in the laboratory or factory by way of a series of chemical reactions from low molecular weight compounds. From your functional perspective they are often classified into four main categories: thermoplastics, thermosets, elastomers and synthetic fibres. Polymethyl methacrylate (PMMA) is one such thermoplastic made by the polymerization of the monomer, methyl methacrylate (MMA). PMMA is commonly generally known as acrylic plastic and lends its properties into a selection of consumer product applications. Being both a thermoplastic and transparent plastic, acrylic is used extensively in the automotive industry in trunk release handles, master cylinder, and dashboard lighting. Consumer goods that use a constituent element of acrylic plastic include aquariums, motorcycle helmet lenses, paint, furniture, picture framing, and umbrella clamps, and others.
Many of the other synthetic polymers we utilization in our everyday life include Nylons, utilized in fabrics and textiles, Teflon, utilized in non-stick pans and Polyvinyl Chloride, utilized in pipes.

Polymers have for very long been a fundamental portion of our everyday lives because of this that examples is available almost ubiquitously. We generally have an impact which leads us to think that polymers are simply plastics used for packaging, in household objects and for making fibres, but this is just the tip with the iceberg.

Polymers are employed in all sorts of applications you may not have thought much about. This web site enlightens you concerning the story behind polymers and the way it has evolved since for everyone several functions across a host of industries.
Origin of polymer science
Humans have got good thing about the flexibility of polymers since way back when available as oils, tars, resins and gums. However, it was not before industrial revolution how the polymer industry began to develop. In fact, the birth of polymer science could possibly be traced returning to the mid-nineteenth century. Inside the 1830s, Charles Goodyear developed the vulcanization process that transformed the sticky latex of natural rubber in to a useful elastomer for tire use.

It had been this resin that served as a harbinger to many people with the common polymers that people use today. The term “polymer” is derived from the Greek roots “poly” and “mer,” which put together means “many parts.” Polymeric substances are comprised of numerous chemical units called monomers, which are joined together into large molecular chains consisting of 1000s of atoms.

Synthetic polymers, as his or her name indicates, are synthesized from the laboratory or factory by having a group of chemical reactions from low molecular weight compounds. Through the functional point of view they can be classified into four main categories: thermoplastics, thermosets, elastomers and artificial fibres. Polymethyl methacrylate (PMMA) is a such thermoplastic manufactured by the polymerization with the monomer, methyl methacrylate (MMA). PMMA is usually generally known as acrylic plastic and lends its properties to some various consumer product applications. Being both a thermoplastic and transparent plastic, acrylic is employed extensively from the automotive industry in trunk release handles, master cylinder, and dashboard lighting.

How do a liquid which includes just 5 carbon atoms, 2 oxygen atoms and 8 hydrogen atoms be used for durable purposes where thermal resistance, electrical resistance and mechanical strength is of prime importance? A better solution is in a word – “Polymerisation”.
Through this infographic, we trace the journey of MMA (Methyl Methacrylate), a liquid monomer that is polymerised to lead to PMMA polymer (Polymethyl Methacrylate), and it is various grades.

MMA can be polymerised to PMMA through solution polymerisation, emulsion polymerisation and bulk polymerisation techniques. These reactions happen in the existence of a catalyst. The resulting acrylic glass can be modified to varied shapes, sizes and forms depending on the additives.
The different grades of SUMIPEX®, the Polymethyl methacrylate resin made by Sumitomo Chemical, which can be obtained on adding additives are:
