ABSTRACT:
A composition of matter with improved mechanical properties which contain 2 - 50 mol. percent of methacrylonitrile or acrylonitrile and 50 - 98 mol. percent of glycol monoesters of acrylic or methacrylic acid, where the glycol is selected from the group comprising ethylene glycol, diethylene glycol, triethylene glycol and their mixtures. 0.1 - 30 mol. percent of the glycol monoesters may be substituted by a crosslinking agent selected from the group comprising 1,4-cyclohexanedimethyl dimethacrylate, ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, 1,6-hexamethylene-bis-acrylamide, triethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate, methylene-bis-acrylamide, ethylene-bis-acrylamide. Also hydrogen catalysts of compositions bonded to platinum, palladium or rhodium metal.
A process for producing the matter, wherein glycol esters of acrylic or methacrylic acid are copolymerized with methacrylonitrile or acrylonitrile, if desired in the presence of a crosslinking agent.
