Document Type and Number:
WIPO Patent Application WO/2021/057074
Kind Code:
A1
Abstract:
A novel high-temperature-resistant high-strength high-light-transmittance cycloolefin copolymer and a preparation method therefor. The cycloolefin copolymer comprises the following raw materials in parts by weight: 35-65 parts of dicyclopentadiene, 10-40 parts of norbornene and derivatives thereof, 3-5 parts of a benzene solvent, 1-3 parts of a ketone solvent, 5-8 parts of an alcohol solvent, 10-15 parts of a high-transparency aid, and 0.01-0.2 part of a catalyst. The preparation method comprises the following steps: in addition to the catalyst, uniformly mixing a liquid material, a transparent auxiliary agent and 5-10 parts of the solvent to prepare a solution A; fully and uniformly mixing the catalyst with 1-5 parts of a solvent to prepare a catalyst solution B; mixing the liquid A and the liquid B according to a certain proportion, uniformly stirring the mixed solution at the room temperature of about 25°C, and mixing the liquid A and the liquid B; pouring the mixed AB liquid into a mold, performing standing treatment for molding the mixture at 45-80°C, and demolding the molded product. The present invention has the characteristics of low density, high strength, excellent temperature resistance, environment-friendly, simple and convenient process and low cost.
