一、引言钛酸酯偶联剂是七十年代发展起来的一种新型偶联剂。据美国Kenrich石油化学公司1974年底报导,在100磅高密度聚乙烯中,添加少量—异丙基三异硬脂酰钛酸酯(商品牌号为TTS),再加入157磅碳酸钙填料(碳酸钙:聚乙烯=61:39)。所得材料之性能与未加填料的聚乙烯相仿。此后,钛酸酯偶联剂在聚丙烯、聚氯乙烯钙塑材料中也相继得到应用。据报导,在聚丙烯—碳酸钙体系中,加入TTS,落地冲击强度可提高6.5倍,在 I. Introduction Titanate coupling agent is developed in the seventies a new type of coupling agent. According to the report by the American Kenrich Petrochemical Company at the end of 1974, a small amount of isopropyl-triisostearoyl titanate (trade number: TTS) was added to 100 pounds of high-density polyethylene followed by 157 pounds of calcium carbonate filler : Polyethylene = 61: 39). The properties of the resulting material are similar to those of unfilled polyethylene. Since then, titanate coupling agent in polypropylene, polyvinyl chloride plastic materials have also been applied. It has been reported that in the polypropylene-calcium carbonate system, adding TTS, floor impact strength can be increased 6.5 times in the
