Title:
RANDOM CYCLOOLEFIN MULTICOMPONENT POLYMER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3237072
Kind Code:
B2
Abstract:
PURPOSE: To obtain a random copolymer excellent in transparency, heat resistance and mechanical properties and also in melt flow by copolymerizing a specified α-olefin with a specified norbornene derivative and a specified cycloolefin.
CONSTITUTION: The copolymer is produced by copolymerizing a 2C or higher α-olefin (A) with a 11C or lower norbornene derivative (B) of formula I (wherein R1 and R2 are each H, halogen, a 4C or lower hydrocarbon group or the like) and a 12C or higher cycloolefin (C) of formula II (wherein n is 0 or 1; m is 0 or a positive integer; q is 0 or 1; R1 to R18, Ra and Rb are each H, halogen, a hydrocarbon group or the like) or of formula III (wherein p and q are each 0 or a positive integer; m and n are each 0, 1, or 2; and R1 to R19 are each H, halogen, a hydrocarbon group, alkoxy or the like) in B to C molar ratio of 85/15-30/70 in a hydrocarbon solvent in the presence of a catalyst comprising a soluble vanadium compound and an organoaluminum compound or a catalyst comprising a metallocene compound of a transition metal selected from the group IVB metals and an organoaluminumoxy compound.
