SILANE GRAFTED COPOLYMERS OF AN ISOMONOOLEFIN AND A VINYL AROMATIC MONOMER
摘要
Curable silylated copolymers based on olefin copolymers comprising at least one C4 to C7 isomonoolefin and a vinyl aromatic monomer (alkyl styrene) are prepared by reacting the olefin copolymer with an olefinically unsaturated hydrolyzable silane in the presence of a free radical generating agent. The silylated copolymers are readily curable by contact with water (moisture) and a silanol condensation catalyst and are particularly useful as the polymeric component in sealant, caulking, adhesive and coating formulations.
