ABSTRACT:
Dispersions of core-shell polymers in caprolactam wherein the core-shell polymer comprises a crosslinked elastomer core and a hard thermoplastic shell prepared by adding an aqueous dispersion of core-shell polymer to an aqueous solution of caprolactam, stirring the mixture to provide a uniform dispersion and evaporating water from the mixture. Such dispersions can be combined with caprolactam polymerization initiator and caprolactam polymerization catalyst to provide rubber-modified nylon-6 polymers.
