Particulate, expandable self-extinguishing styrene polymers showing good processability |
摘要 |
Particulate, expandable styrene polymers containing a flame-proofing organic halo compound as expanding agent and also a mixture of from 2.5 to 30% by weight of a hydrocarbon of from 3 to 6 carbon atoms and from 97.5 to 70% by weight of monofluorotrichloromethane, based on the total weight of said mixture serving as expanding agent, show good processability and exhibit self-extinguishing properties even during processing.
