Network Formation in Free Radical Polymerization

  • H. Tobita

Kinetic models for crosslinking and cyclization in free radical polymerization of vinyl/divinyl monomers are proposed. In free radical polymerization each primary polymer molecule experiences a different history of crosslinking and cyclization, and therefore, a polymer network possesses “a crosslinkng density distribution”. The variance of this distribution becomes significant when the polymerization conditions deviate from Flory’s simplifying assumptions. The concept of crosslinking density distribution makes it possible to generalize Flory’s theory of network formation.
