POLYPHENYLENE ETHER-ALKENYL AROMATIC POLYMER BLENDS HAVING ORGANOBROMINE ADDITIVES

Certain organobromines are added to blends of polyphenylene ether and alkenyl ar omatic 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 organobromi...

Zusammenfassung:	Certain organobromines are added to blends of polyphenylene ether and alkenyl ar omatic 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 inve ntion are as follows: tetrabromocyclooctane, hexa-bromocyclododecane, tetrabromovinylcyclohexene and bis(allyl ether) of tetr abromobisphenol.
