摘要:
organopolysiloxane. the present invention provides an organopolysiloxane obtained by binding to at least two silicon atoms of an organopolysiloxane segment that constitutes a main chain, a poly (n-acylalkyleneimine) segment comprising a repeating unit represented by the following formula (1): in that r ^ 1 ^ represents a hydrogen atom or an alkyl group having from 1 to 3 carbon atoms and n represents 2 or 3, through an alkylene group containing a heteroatom, where the poly (n-acylalkyleneimine) segment has a molecular weight numerical average of 1,600 to 3,500; a weight ratio of (a / b) of the organopolysiloxane segment (a) that constitutes the backbone for the poly (n-acylalkyleneimine) segment (b) (hereinafter simply referred to as the (a / b) weight ratio)) is 42/58 and 58/42; the organopolysiloxane segment between two poly (n-acylalkyleneimine) segments adjacent to each other has an average molecular weight of 1,600 to 3,500 and the organopolysiloxane segment that constitutes the main chain has an average molecular weight of 7,000 to 100,000.organopolissiloxano. a presente invenção fornece um organopolissiloxano obtido por ligação a pelo menos dois átomos de silício de um segmento organopolissiloxano que constitui uma cadeia principal, um segmento poli (n-acilalquilenoimina) compreendendo uma unidade de repetição representada pela fórmula (1) que se segue: em que r^ 1^representa um átomo de hidrogênio ou um grupo alquila apresentando de 1 a 3 átomos de carbono e n representa 2 ou 3, através de um grupo alquileno contendo um heteroátomo, onde o segmento poli (n-acilalquilenoimina) apresenta um peso molecular médio numérico de 1.600 a 3.500; uma razão em peso de (a/b) do segmento organopolissiloxano (a) que constitui a cadeia principal para o segmento poli (n-acilalquilenoimina) (b) (doravante denominada simplesmente "razão em peso de (a/b)") é de 42/58 e 58/42; o segmento organopolissiloxano entre dois segmentos poli (n-acilalquilenoimina) adjacentes um ao outro
