The radical‐induced grafting of n ‐butyl acrylate (BA) onto poly(butadiene‐ co ‐styrene) [(P(Bd‐S)] latexes during seeded emulsion polymerization was studied. This P(Bd‐S)/PBA rubber/rubber core/shell latex system exhibited unique grafting behavior as compared to other extensively studied rubber/glass core/shell latex systems, such as poly(butadiene‐ co ‐styrene)/poly(methyl methacrylate) [P(Bd‐S)/PMMA], poly(butadiene‐ co ‐styrene)/polystyrene [P(Bd‐S)/PS] and poly(butadiene‐ co ‐styrene)/poly(acrylonitrile)[P(Bd‐S)/PAN]. These composite latexes were characterized by the formation of a highly grafted/crosslinked P(Bd‐S)/PBA interphase zone generated during the seeded emulsion polymerization process. Although both of the individual core and shell polymers studied were “soft” themselves, the resulting P(Bd‐S)/PBA composite latex particles were found to be rather “hard.” The formation of the interphase zone was studied by using techniques such as solvent extraction, differential scanning calorimetry (DSC), and transmission electron microscopy (TEM). © 1997 John Wiley & Sons, Inc.
