(57) [Summary] (with correction) [Problem] A viscosity number greater than 20 cm 3 / g and 100 Find a method that makes it possible to obtain a polymer with a glass transition temperature above 0 ° C. [Solution] 0.1 to 100% by weight based on the total amount of monomers % Of formula I, II, III or IV (Wherein, R 1 to R 8 represent H or an alkyl group of C 1 to C 8 ), and 0 to 99.9% by weight of a compound represented by the formula V based on the total amount of the monomers. Wherein n is a number of 2 to 10. 0 to 99.9 wt. % Formula VI (Wherein, R 9 to R 12 represent H or an alkyl group of C 1 to 8) represented by the following formula: at least one acyclic 1-olefin represented by the following formula: Cycloolefins prepared by polymerization in the gas phase at a temperature of -78 to 150 ° C and a pressure of 0.5 to 64 bar in the presence of a specific catalyst comprising a metallocene and aluminoxane as transition metal components polymer. |
