Title
(DE) ORGANOPOLYSILOXAN-PFROPFPOLYMER
(EN) ORGANOPOLYSILOXANE GRAFT POLYMER
(FR) POLYMÈRE D'ORGANOPOLYSILOXANE GREFFÉ
Abstract
(EN) The present invention relates to an organopolysiloxane graft polymer including an organopolysiloxane segment as a main chain thereof and an unsaturated monomer-derived copolymer segment containing a repeating unit derived from an unsaturated monomer containing a carboxylic acid or a carboxylic acid salt as a side chain thereof, in which a content of the organopolysiloxane segment in the organopolysiloxane graft polymer is 35 to 59% by mass, a content of the repeating unit derived from the unsaturated monomer containing a carboxylic acid or a carboxylic acid salt in the organopolysiloxane graft polymer is 4 to 17% by mass, and a content of a repeating unit derived from an unsaturated monomer whose homopolymer has a glass transition point of not lower than 150°C (except for the unsaturated monomer containing a carboxylic acid or a carboxylic acid salt) in the organopolysiloxane graft polymer is not more than 14% by mass, and a number-average molecular weight of the organopolysiloxane segment is not less than 8,000 and not more than 200,000.
(FR) La présente invention porte sur un polymère d'organopolysiloxane greffé qui a un segment organopolysiloxane en tant que chaîne principale et un segment copolymère issu d'un monomère insaturé en tant que chaîne latérale, le segment copolymère contenant un motif répété issu d'un monomère insaturé comprenant un acide carboxylique ou un sel de celui-ci, la teneur du segment organopolysiloxane étant de 35 à 59 % en masse, la teneur du motif répété issu d'un monomère insaturé comprenant un acide carboxylique ou un sel de celui-ci étant de 4 à 17 % en masse, la teneur d'un motif répété issu d'un monomère insaturé (à l'exclusion d'un monomère insaturé comprenant un acide carboxylique ou un sel de celui-ci) ayant une propriété telle qu'un homopolymère formé à partir de celui-ci a une température de transition vitreuse supérieure ou égale à 150°C étant inférieure ou égale à 14 % en mase dans le polymère d'organopolysiloxane greffé et le segment organopolysiloxane ayant une masse moléculaire moyenne en nombre de 8 000 à 200 000 inclus.
