对炔基有机硅烷及多苯芳烃基有机硅烷的研究,文献中已有少量报导。多苯芳烃基有机硅化合物具有很好的耐高温性能,有的用作高温硫化硅橡胶的添加剂,有的用作室温硫化硅橡胶的交联剂,还有的用来制备耐高温树脂、涂料等。炔基硅烷可以用来合成多苯芳烃基有机硅烷,利用含炔基的二氯硅烷可以得到侧链为炔基的硅—硅链高聚物。对硅—硅链高聚物的研究,近年来发展的很快。人们发现,这类聚合物具有许多特殊的
There have been few reports of alkynyl organosilanes and polybenzalmylorganosilanes in the literature. Polybenzyl aromatic organosilicon compounds have good high temperature performance, and some for high temperature vulcanized silicone rubber additives, some for room temperature vulcanized silicone rubber crosslinking agent, and some used to prepare high temperature resins, coatings Wait. Alkynylsilanes can be used to synthesize polybenzalmylorganosilanes. Silicon alkoxide-containing silicon-silicon chain polymers can be obtained from alkynyl-containing dichlorosilanes. The research on silicon-silicon chain polymer has developed rapidly in recent years. It has been found that such polymers have many unique properties
