摘要：
Certain organobromines are added to blends of polyphenylene ether and alkenyl aromatic polymer to reduce mold cool time of the composition. These organobromines also reduce residual blowing agent in the composition after expansion and especially following molding of the composition. The organobromines of this invention are as follows:tetrabromocyclooctanehexabromocyclododecanetetrabromovinylcyclohexenebis(allyl ether) of tetrabromobisphenol A
