Abstract
A method for melt-processing a polymer of a monovinyl aromatic compound, such as styrene, is disclosed. The method may include heating a polymer of a monovinyl aromatic compound volumetrically with microwave energy, wherein the polymer of a monovinyl aromatic compound includes: a discontinuous rubber phase; and a continuous poly(monovinyl aromatic) phase comprising up to 49 weight percent of at least one of an acrylate comonomer and a vinyl cyanide comonomer.
