Title (EN) INTERNAL RESIN-TACKIFIED ACRYLIC POLYMERS CONTAINING CROSSLINKABLE COMONOMERS
(FR) POLYMERES ACRYLIQUES RENDUS COLLANTS PAR UNE RESINE INTERNE, CONTENANT DES COMONOMERES RETICULABLES
Abstract:
(EN) Acrylic copolymer compositions which contain a tackifying hydrocarbon resin and a polyfunctional crosslinking monomer and the use of such composition in pressure-sensitive adhesives are described. The tackifying hydrocarbon resin is dissolved, as is the polyfunctional monomer, in a solution of alkyl(meth)acrylate and (meth)acrylic acid monomers and is present during the polymerization of the monomers to form a tackified acrylic copolymer. Acrylic copolymer compositions which contain a tackifying hydrocarbon resin and a polyfunctional crosslinking monomer and the use of such composition in pressure-sensitive adhesives are described. The tackifying hydrocarbon resin is dissolved, as is the polyfunctional monomer, in a solution of alkyl (meth)acrylate and (meth)acrylic acid monomers and is present during the polymerization of the monomers to form a tackified acrylic copolymer.
(FR) Sont décrites une composition de copolymère acrylique contenant une résine d'hydrocarbure rendant adhésif ainsi qu'un monomère de réticulation polyfonctionnelle, et l'utilisation de ladite composition dans des adhésifs autocollants. La résine d'hydrocarbure rendant adhésif est dissoute ainsi que le monomère polyfonctionnel, dans une solution de monomères d'alkyl (meth) acrylate et d'acide (meth) acrylique, et elle est présente pendant la polymérisation des monomères afin de former un copolymère acrylique rendu adhésif.
