Abstract: Disclosed is a composition comprising a polycarbonate or engineering resin and a branched polymer which is a reaction product of reactants comprising one or more monoethylenically unsaturated ester monomers, a chain transfer agent in an amount of 0.1 to 10 weight percent, and a crosslinker in an amount of 0.1 to 10 weight percent of a crosslinker, wherein weight percent is based on total amount of reactants, provided the amount of crosslinker in moles is less than the effective amount of chain transfer agent in moles, and articles thereof.
