Process for the preparation of fire-retardant expandable thermoplastic beads. |
摘要 |
<p>Fire-retardant expandable vinyl aromatic polymer beads are prepared by an aqueous suspension method whereby a bromophenyl allyl ether fire-retardant agent and a volatile aliphatic hydrocarbon foaming agent are incorporated into particles of a thermoplastic such as polystyrene. The beads are useful in the preparation of molded foam articles having excellent resistance to flame.</p> |
