Title:
POLYMERIZATION OF INDENE
Document Type and Number:
Japanese Patent JPH01167314
Kind Code:
A
Abstract:
PURPOSE:To obtain noncrystalline polyindene with high glass transition temperature, good in transparency, low in birefringence, useful as a heat-resistant polymer or optical material, by polymerization of indene using a specific catalyst. CONSTITUTION:The objective polyindene can be obtained by polymerization of indene in the presence of a catalyst consisting of (A) a vanadium-contg. catalytic component [e.g., a compound of the formula V0(OR)pXq or the formula V(OR)rXs (X is halogen; R is 1-22C hydrocarbon; p and q are each 0-3, p+q=2-3; r and s are each 0-4, r+s=3-4); specifically, VOCl3, VO(OC2H5) Cl3] and (B) a halogenated organoaluminum compound catalytic component [e.g., a compound of the formula AlXnR3-n (X is halogen; R is 1-12C hydrocarbon; n is 1-2); specifically, Al(C2H5)Cl]. The molar ratio: Al/V is pref. 3-100.
