POLYPROPYLENE/ORGANOPOLYSILOXANE COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene/organopolysiloxane copolymer having a structure in which the organopolysiloxane part and the polypropylene part are bonded to each other. SOLUTION: This copolymer is obtained by subjecting a first component comprising an organohydrogenpolysiloxane having H-bonded silicon atoms at both ends and a second component comprising anα,ω-diene/propylene polymer to a hydrosilylation reaction. The first component is desirably an organohydrogenpolysiloxane represented by the formula: R<1> R<2> HSi-(OSiR<3> R<4> )m - OSiHR<1> R<2> (wherein R<1> and R<2> are each methyl; R<3> and R<4> are each a 1-5C alkyl or an aryl; and (m) is an integer of 0 or greater).
