Schlagzäh thermoplastische Formmasse

摘要

The invention concerns a mixture of a copolymer (A) comprising between 50 and 99 mol % polymerized-in styrene units and between 1 and 50 mol % polymerized-in units of 1,1-diphenylethylene and/or a block copolymer comprising at least one polystyrene block and at least one poly(styrene/diphenylethylene) block of the above composition. The invention further concerns a process for preparing this mixture by the anionic block (co)polymerization of styrene or styrene and diphenylethylene, and an impact-resistant modified polystyrene (B).
