摘要： A composite polymer composition comprising: the emulsion polymerization product of: (i) an aqueous polyolefin dispersion comprising the melt kneading product of one or more polyolefins, from 2 to 25 wt % of one or more dispersion stabilizing agents and water, and (ii) one or more (meth)acrylic monomers; wherein the one or more polyolefins have a Tg equal to or less than 50° C.; and wherein the melt kneading product (i) comprises polymer particles having a volume average particle size between 150 nm and 2000 nm dispersed in the water; and wherein the one or more (meth)acrylic monomers polymerize onto the polymer particles form composite polymer particles is provided. Also provided is a method of making the composition and impact modifiers comprising the composition.
