Title:
STATISTICAL COPOLYMER LATEX AND USE THEREOF, AND PRODUCTION METHOD FOR STATISTICAL COPOLYMER LATEX
Document Type and Number:
WIPO Patent Application WO/2019/211975
Kind Code:
A1
Abstract:
Provided is a technology for improving the alcohol-added gasoline resistance and engine oil resistance of a statistical copolymer obtained by drying a statistical copolymer latex. This statistical copolymer latex comprises a chloroprene monomeric unit and an unsaturated nitrile monomeric unit, the contained amount of the unsaturated nitrile monomeric unit being 5-20 mass%, wherein the contained amount of the toluene-insoluble fraction of a statistical copolymer obtained by lyophilization of the statistical copolymer latex is 50-100 mass% with respect to 100 mass% of the statistical copolymer.
