Tetrabromobisphenol-A polycarbonate (TBBPA-PC) was synthesized by interfacial polymerization with triphosgene (BTC) and tetrabromobisphenol a (TBBPA) as raw materials.
以三光气(BTC)和四溴双酚a (TBBPA)为原料,经界面缩聚合成了高分子量四溴双酚a聚碳酸酯。

The triphosgene, being as the substitute for phosgene and diphosgene in synthesis, is not only low-toxic but also safe and convenient to use with mild conditions, good selectivity and high yields.
The risk of reaction using phosgene could be avoided effectively by substitution of triphosgene for phosgene, and application of triphosgene in production with broad prospect was believed by author.
