Project at a Glance Contents on the CD ROM
  • 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.
