Plastics are Organic synthetic materials. Chemistry of Plastics The polymerization process. This way the monomers are joined together in a sequence to grow in a specific way. The monomer word plastic is derived from the Greek word meanings ''to grow''. Hence it is synthesized by there are joined together in straight chain or branched chain. It decides the nature of plastic that it would be thermosetting or thermoplastics. The raw materials are of organic in nature i.e natural gas, oils,or plants. By refining the raw materials ethene or propene gas are obtained that are basics raw materials and when the cracking of ethene and propene are obtained this ethylene or propylene is basically, used as monomers in the polymerization of plastic but the derivatives of ethylene or propylene are also used. These derivatives are PVC, nylon, styrene, polyamide, poly-acetate etc. Types of plastics 1. Thermoplastics: ...
