Abstract
Disclosed is a composition comprising a polyolefin and a core-shell acrylic polymer comprising a crosslinked core and a shell comprising a branched polymer. The branched polymer 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 15 weight percent, and a crosslinker in an amount of 0.1 to 15 weight percent of a crosslinker, wherein weight percent is based on total amount of reactants, provided the amount of crosslinker is within +/−5 weight percent of the amount of chain transfer agent, and wherein the crosslinker comprises at least two carbon-carbon double bonds having different reactivity. A method for preparing the composition is also disclosed.
