Patent

CA 2438015

A low gloss thermoplastic molding composition comprising a grafted acrylate rubber (ASA) and a process for its preparation are disclosed. The composition contains an effective amount of a gloss-reducing agent that is the reaction product of (i) compound having two or more maleic anhydride groups per molecule and (ii) compound having two or more terminal primary amine groups per molecule. The incorporation of the gloss reducing agent in the inventive composition may be by blending the reaction product or, in the alternative, blending the reactants (i) and (ii) in the molten ASA under process conditions designed to bring about the in situ formation of the inventive gloss reducing agent.

L'invention décrite dans le présent document concerne une composition de moulage thermoplastique peu lustrée comprenant substrat greffé en caoutchouc de type acrylate (ASA) et un procédé de préparation connexe. Cette composition contient une quantité efficace d'un agent réducteur de brillance qui est le produit de la réaction de i) un composé ayant au moins deux groupes d'anhydride maléique par molécule et ii) un composé ayant au moins deux groupes d'amines primaires terminaux par molécule. L'incorporation de l'agent réducteur de brillance dans la composition selon l'invention peut se faire soit en mélangeant le produit de la réaction, soit en mélangeant les réactifs i) et ii) dans le caoutchouc de type acrylate (ASA) fondu dans des conditions de traitement conçues pour provoquer la formation in situ de l'agent réducteur de brillance selon l'invention.
