Impact modified polystyrene and process for preparing same

摘要

Disclosed is a composition comprising an impact modified polystyrene prepared using a process comprising dissolving a styrene-butadiene-styrene block copolymer in styrene monomer and polymerizing the styrene monomer wherein the impact modified polystyrene has a haze value of less than or equal to 12 percent. Also disclosed is an impact modified polystyrene prepared using the same process and having a ratio of Mz/Mn of at least 4.1.
