ABSTRACT:
A solid state insoluble salt catalyst system for the carbocationic polymerization of olefin monomer in the presence of a polar or non-polar reaction medium, which comprises (a) solid state catalyst component comprising at least one salt of a strong acid and a carbocationically active transition metal selected from Groups III A, IV A, V A and VI A of the Periodic Table of Elements, wherein said salt is insoluble in the reaction medium; and (b) cocatalyst component effective for promoting the carbocationic polymerization.
