Title:
CYCLOOLEFIN COPOLYMER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/176588
Kind Code:
A1
Abstract:
A cycloolefin copolymer has a structure represented by formula I, II, III or IV, wherein in the formula I, 100≤x≤350, 25≤y≤150; in the formula II, 300≤z≤1000; in the formula III, 180≤m≤430, 40≤n≤220; and in the formula IV, 250≤i≤500, 20≤j≤144. The present invention provides a method for preparing a cycloolefin copolymer. The method comprises: under the effect of a catalyst, a first compound and a second compound are subjected to polymerization reaction in a solvent to obtain a polymerization reaction product; and the polymerization reaction product and a hydrogen source are subjected to hydrogenation reaction to obtain a cycloolefin copolymer, wherein the first compound has a structure represented by formula 1, and the second compound has a structure represented by formula 1, 2, 3 or 4. The cycloolefin copolymer provided by the present invention has good thermal resistance and mechanical performance.
