Title:
CYCLIC CONJUGATED DIENE COPOLYMER AND MANUFACTURING METHOD FOR HYDROGENATE OF THE SAME
Document Type and Number:
Japanese Patent JP2005255732
Kind Code:
A
Abstract:

To provide a manufacturing method for a hydrogenated cyclic conjugated diene copolymer excellent in impact resistance, heat resistance and transparency, and a resin molded product for optical applications made of the same.

The manufacturing method for the hydrogenated cyclic conjugated diene copolymer comprises hydrogenating a random copolymer having a 1,2-linkage comprising 80-95 pts. wt. of a cyclic conjugated diene monomer and 5-20 pts. wt. of a linear conjugated diene monomer. The resin molded product for optical applications is made of the same.
