Abstract
An impact resistant thermoplastic polymer comprising highly occluded rubbery particles is prepared by contacting an emulsion of a rubbery polymer with at least one addition polymerizable, graftable monomer under conditions such that the rubber emulsion particles imbibe the monomer, but substantially no monomer polymerization occurs followed by free radically polymerizing the monomer and thereafter repeating steps (a) and (b) at least one more time.
