Styrene polymers containing blowing agents |
September 20, 1988 |
| Particulate styrene polymers containing blowing agents are prepared by a process in which an aliphatic hydrocarbon of 7 to 9 carbon atoms is added in an amount of from 0.01 to 0.5% by weight, based on the styrene polymer, before, during or after the polymerization. The particulate styren |
