Abstract

PURPOSE:To obtain the titled copolymer having hydroxyl groups and epoxy groups in the molecule and having a relatively high hydroxyl group content, by copolymerizing a diene monomer with an epoxy group-containing monomer in the presence of H2O2. CONSTITUTION:0.1-50pts.wt. aqueous H2O2 solution of a concentration of 30-80% is added to 100pts.wt. monomer mixture comprising 50-98wt% 4-12 C diolefinically unsaturated unsubstituted, 2-substituted or 2,3-disubstituted 1,3-diene monomer (e.g., 1,3-butadiene) and 50-2wt% epoxy group-containing monomer, and the resulting mixture is copolymerized at 5-200 deg.C and a pressure of 0-200kg/cm<2>G for 0.1-24hr with agitation in 5-500wt%, based on the total feed, solvent (e.g., methanol). In this way, a liquid diene copolymer useful as an elastic sealant, adhesive, lining material, coating agent or electron beam-resist material can be obtained.
