Abstract:
(EN) In order to provide a flexible composition, the present invention provides a composition containing a graft copolymer in which a monomer having (meth)acrylonitrile and a (meth)acrylate ester as main components thereof is graft-copolymerized with a main-chain polymer having a polyvinyl alcohol, the degree of saponification of the polyvinyl alcohol being 50-100 mol%, the content of the polyvinyl alcohol being 5-50% by mass, the total amount of the (meth)acrylonitrile monomer units and the (meth)acrylate ester monomer units being 50-95% by mass, the content of the (meth)acrylonitrile monomer units in a total of 100% by mass of the (meth)acrylonitrile monomer units and the (meth)acrylate ester monomer units being 20-95% by mass, the content of the (meth)acrylate ester monomer units in a total of 100% by mass of the (meth)acrylonitrile monomer units and the (meth)acrylate ester monomer units being 5-80% by mass, and the (meth)acrylate ester being a monomer whereby the glass transition temperature of a poly(meth)acrylate ester homopolymer composed solely of the (meth)acrylate ester is 150-300 K.
(FR) Dans le but de réaliser une composition souple, la présente invention concerne une composition contenant un copolymère greffé dans lequel un monomère comportant en tant que constituants principaux du (méth)acrylonitrile et un ester (méth)acrylate est copolymérisé par greffage avec un polymère à chaîne principale comprenant un poly(alcool vinylique), le degré de saponification du poly(alcool vinylique) étant de 50 à 100 % en moles, la teneur en poly(alcool vinylique) étant de 5 à 50 % en masse, la quantité totale des motifs monomères (méth)acrylonitrile et des motifs monomères ester (méth)acrylate étant de 50 à 95 % en masse, la teneur en les motifs monomères (méth)acrylonitrile, pour 100 % en masse de la somme des motifs monomères (méth)acrylonitrile et des motifs monomères ester (méth)acrylate étant de 20 à 95 % en masse, la teneur en les motifs monomères ester (méth)acrylate pour 100 % en masse du total des motifs monomère (méth)acrylonitrile et des motifs monomères ester (méth)acrylate étant de 5 à 80 % en masse, et l'ester (méth)acrylate étant un monomère tel que la température de transition vitreuse d'un homopolymère de poly(ester (méth)acrylate)), constitué uniquement de l'ester (méth)acrylate, soit de 150 à 300 K.
(JA) 柔軟性を有する組成物の提供。 ポリビニルアルコールを有する幹ポリマーに、(メタ)アクリロニトリル及び(メタ)アクリル酸エステルを主成分とする単量体がグラフト共重合したグラフト共重合体を含有し、前記ポリビニルアルコールの鹸化度が50~100モル%であり、前記ポリビニルアルコールの含有量が5~50質量%であり、前記(メタ)アクリロニトリル単量体単位及び前記(メタ)アクリル酸エステル単量体単位の合計量が50~95質量%であり、前記(メタ)アクリロニトリル単量体単位及び(メタ)前記アクリル酸エステル単量体単位の合計100質量%中の前記(メタ)アクリロニトリル単量体単位の含有量が20~95質量%であり、前記(メタ)アクリロニトリル単量体単位及び前記(メタ)アクリル酸エステル単量体単位の合計100質量%中の(メタ)アクリル酸エステル単量体単位の含有量が5~80質量%であり、前記(メタ)アクリル酸エステルは、前記(メタ)アクリル酸エステルのみより構成されるポリ(メタ)アクリル酸エステルホモポリマーのガラス転移温度が150~300Kである単量体である、組成物。
