Abstract

The rate of polymerization of cycloolefins is to a very high degree dependent on the catalyst used and so is the induction period. The order of the reaction with respect to monomer and catalyst concentration as well as activation energy and entropy have been determined. Product distribution and configuration of the double bonds initially are kinetically controlled. The thermodynamics of the polymerization of cycloolefins are discussed in terms of ring size. The reaction products generally consist of cyclic oligomers and an acyclic polymer. As equilibrium is approached, above a certain minimum initial monomer concentration (cut-off point) an invariable concentration of oligomers is obtained. With increasing monomer concentration an increasing amount of polymer is formed. The concentration of cyclics is discussed in terms of a ring—chain equilibrium.
