Title:
HYDROGENATED CYCLOPENTADIENE RESIN, ITS PRODUCTION AND OPTICAL MATERIAL, MEDICAL MATERIAL, ELECTRICAL INSULATION MATERIAL AND ELECTRONIC PART TREATING MATERIAL MADE FROM THE RESIN
Document Type and Number:
Japanese Patent JPH06136057
Kind Code:
A
Abstract:
PURPOSE: To obtain a resin free from cross-linked gelatinous component and having high transparency, low birefringence and excellent light-resistance, moisture resistance, moldability, electrical characteristics and mechanical strength.
CONSTITUTION: The resin having an intrinsic viscosity [η] of 0.1-10dl/g in toluene at 25°C is produced by subjecting monomers composed mainly of a cyclopentadiene compound to linear addition polymerization and hydrogenating at least 90% of the recurring unit originated from the cyclopentadiene compound. The resin is useful as an optical material, medical material, electrical insulation material and material for treating electronic part.
