ABSTRACT:
The flow properties of styrenic polymer resins derived from at least one monovinylidene aromatic compound and, optionally, other copolymerizable monomers, are improved by copolymerizing from 0.1 to 15 weight percent of an ester of acrylic acid, e.g., n-butylacrylate, with the monovinylidene aromatic compound and any other copolymerizable monomers employed in preparing the styrenic polymer resin.
