Vinyl polymers are a group of polymers derived from vinyl monomers Their backbone is an extended alkane chain, made polymerizing an alkene group (C=C) into a chain (..-C-C-C-C-..). In popular usage, "vinyl" refers only to polyvinyl chloride (PVC). Vinyl polymers are the most common type of plastic. For amorphous polymers, the transition from liquid-like to glass-like behavior is called the glass transition. There are several means to modify polymers properties, viz. blending, grafting, and curing. Blending is the physical mixture of two (or more) polymers to obtain the requisite properties. Grafting is a method wherein monomers are covalently bonded (modiﬁed) onto the polymer chain Whereas in curing, the polymerization of an oligomer mixture forms a coating which adheres to the substrate by physical forces. Curing gives a smooth ﬁnish by ﬁlling in the valleys in the surface. In rubber/elastomer industries, crosslinking is the most important reaction of vinyl polymers •Vulcanization: using peroxide, sulfur or sulfur containing compounds •Free radical reactions by ionizing radiation •Photolysis involving photo sensitive funcitonal groups •Chemical reactions of labile functional groups Photoinitiated free radical polymerization consists of four distinct steps: 1. Photoinitiation: Absorption of light by a photosensitive compound or transfer of electronic excitation energy from a light absorbing sensitizer to the photo sensitive compound. Homolytic bond rupture leads to the formation of a radical, that reacts with one monomer unit. 2. Propagation: Repeated addition of monomer units to the chain radical produces the polymer backbone. 3. Chain transfer: Termination of growing chains by hydrogen abstraction from various species (e.g., from solvent) and concomitant production of a new radical capable of initiating another chain reaction. 4. Termination: Chain radicals are consumed by disproportionate or recombination reactions.
