Title
(EN) HIGHLY PROCESSABLE FLEXIBLE ACRYLIC RESIN
(FR) RÉSINE ACRYLIQUE SOUPLE HAUTEMENT TRANSFORMABLE
Abstract
(EN)
Disclosed is a composition comprising a multi-stage flexible acrylic resin and a branched polymer which is a reaction product of reactants comprising one or more monoethylenically unsaturated ester monomers, a chain transfer agent in an amount of 0.1 to 10 weight percent, and a crosslinker in an amount of 0.1 to 10 weight percent of a crosslinker, wherein weight percent is based on total amount of reactants, provided the amount of crosslinker in moles is less than the amount of chain transfer agent in moles, and films thereof.
(FR)
L'invention concerne une composition comprenant une résine acrylique souple à plusieurs étages et un polymère ramifié qui est un produit de réaction de réactifs comprenant un ou plusieurs monomères d'ester monoéthyléniquement insaturés, un agent de transfert de chaîne dans une quantité de 0,1 à 10 % en poids, et un agent de réticulation dans une quantité de 0,1 à 10 % en poids d'un agent de réticulation, le pourcentage en poids étant basé sur la quantité totale de réactifs, la quantité d'agent de réticulation en moles étant inférieure à la quantité d'agent de transfert de chaîne en moles, et des films de celui-ci.
