Estimating the term…
A modified styrenic polymer is described, which comprises the reaction product of said polymer with an ethylenically unsaturated grafting agent having the formula: ##STR1## wherein one to three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are moieties containing reactive groups selected from carboxylic acid, acid anhydride, acid amide, imido, carboxylic ester, amino, hydroxyl, epoxy, isocyanate, carbamate, carbamoyl lactam, acyl lactam, pyridyl, 1,3-oxazoline, 1,3 oxazine, oxazolone, oxazinones, and any derivatives, combinations and mixtures thereof; and wherein the remaining one to three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or a hydrocarbon radical of from about 1 to about 20 carbon atoms; said modified styrenic polymer containing said reactive groups as pendant reactive functionalities. The claimed composition comprises: A) maleated ABS B) polyester C) optionally ethylene copolymer rubber.
A blended composition comprising (a) modified styrenic polymer wherein said modified styrenic polymer comprises the reaction product of polybutadiene modified styrene acrylonitrile resin with an ethylenically unsaturated grafting agent, said grafting agent being maleic anhydride and said modified styrenic polymer containing the acid anhydride groups of said maleic anhydride as pendant reactive functionalities and (b) polyester.
