ABSTRACT:
Styrenic polymer beads that are useful in forming foamed cups with improved strength and thermal properties are prepared by forming an aqueous suspension of initial styrenic polymer beads and adding thereto an emulsion of a comonomer solution of styrenic monomer and divinylbenzene, which emulsion also contains free-radical-producing catalysts, and the suspension with added monomers is heated to copolymerize the styrenic monomer and divinylbenzene within and on the initial beads and form modified beads.
