WIPO Patent Application WO/2011/062077

Kind Code:

A1

Abstract:

Provided is an organopolysiloxane segment formed as a poly(N-acyl-alkylene-imine) comprising a repeating unit represented by general formula (1) (in the formula, R1 represents a hydrogen atom or a C1-3 alkyl group, and n is 2 or 3) binds, via an alkylene group containing hetero atoms, to at least two silicon atoms of an organopolysiloxane segment constituting the main chain, wherein: the number-average molecular weight of the poly(N-acyl-alkylene-imine) segment is 1,600 to 3,500; the mass ratio of the organopolysiloxane segment (a) constituting the main chain and the poly(N-acyl-alkylene-imine) segment (b) (hereinafter referred simply as "mass ratio (a/b)") is 42/58 to 58/42; the weight-average molecular weight of the organopolysiloxane segment between the neighboring poly(N-acyl-alkylene-imine) segments is 1,600 to 3,500; and the weight-average molecular weight of the organopolysiloxane segment constituting the main chain is 7,000 to 100,000.
