[1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered.
Vinyl polymers are the most common type of plastic. Important examples can be distinguished by the R group in the monomer H 2 C=CHR: Polyethylene R = H; polypropylene from propylene, R = CH 3; Polystyrene is made from styrene, R = C 6 H 5; Polyvinyl chloride (PVC) is made from vinyl chloride, R= Cl; Polyvinyl acetate (PVAc) is made from vinyl ...
