THIOL-CONTAINING LIQUID RUBBER COMPOSITION

摘要

Disclosed is a rubber composition comprising a styrene-butadiene copolymer and having improved compatibility with a thiol crosslinking agent and also having increased curability. Specifically disclosed is a thiol-containing liquid rubber composition, comprising (A) a styrene-butadiene copolymer which is liquid at 25°C and (B) a polythiol derived from mercaptocarboxylic acid, wherein the styrene-butadiene copolymer (A) preferably has a bound styrene content of 20 to 90% by mass.
