Abstract: A sound damping composition comprises an acrylic vibrational damping polymer disposed on a surface of a filler. The acrylic vibrational damping polymer has a glass transition temperature, Tg, ranging from −60° C. to less than 10° C., as calculated by the Fox equation, and has a non-crosslinked component having a Tg less than −10° C. The weight ratio of the acrylic vibrational damping polymer to the filler is less than 1:1. A thermoplastic resin composition comprises the sound damping composition and a thermoplastic resin, where the sound damping composition is present in an amount of at least 10 wt % relative to the total weight of the thermoplastic resin composition. Articles produced from the resin composition are also disclosed.

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.
