    Abstract: Disclosed are styrenic polymers made by a mass or solution process, where the amount of trimer consisting of styrene and/or acrylonitrile is less than about 0.50 weight percent. Also disclosed is a method of minimizing the amount of trimer consisting of styrene and/or acrylonitrile in styrenic polymers made by a mass or solution process. The method includes the steps of lowering the temperature of the polymerization reaction mixture and including more than one initiator in the polymerization reaction mixture.
