专利汇可以提供Production of modified liquid polyisoprene type rubber专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain titled rubber having excellent adhesiveness and curability and being useful for sealants, adhesives, etc., by reacting an aminoalcohol with a product prepared by adding maleic anhydride to a liquid polyisoprene type rubber and dehydrating the resulting product.
CONSTITUTION: A modified liquid polyisoprene type rubber having added N-hydroxyhydrocarbyl-maleimide is produced by adding maleic anhydride to a liquid polyisoprene type rubber, viscosity-average MW 15,000W100,000, vinyl addition content ≤25%, weight-average MW/number-average MW ≤4, (the amount of maleic anhydride is 0.35W10.5mol per monomer unit of the liquid isoprene type rubber) reacting the product with an aminoalcohol of the fomula: H
2 N-R-OH, wherein R is an alkyl, an aryl or an aralkyl, e.g., 1-aminopropane-2-o1, and dehydrating the resulting product. The modified rubber thus produced is excellent in curability and adhesion to metal, glass, concrete, etc., and has utility in sealants, adhesives and in asphalt modification and epoxy resin modification, etc.
