The present invention relates to a rubbery polymer having improved properties, characterized in that it comprises repeating units derived from (a) butyl acrylate, or optionally from a mixture of butyl acrylate and ethyl acrylate. 2-ethylhexyl containing up to about 40% 2-ethylhexyl acrylate, (b) at least one compound selected from methyl methacrylate, ethyl methacrylate, methyl acrylate and d acrylate ethyl, (c) acrylonitrile, (d) styrene and (e) a crosslinking agent; a chemical agent or a (co) polymer with hydroxyl group, ester group, amine group or acid group, being grafted onto said rubbery polymer. It also relates to a process for preparing rubbery polymers. |
