1995年7月25日修订的手册。聚碳硅烷由于其不同于一般烃类聚合物的优良特性，近年来受到了广泛的关注。1 '2发展合成方法以获得定义明确的聚碳硅烷对于详细研究聚碳硅烷的化学和物理性质及其在功能材料中的应用是必不可少的。在许多种类的聚碳硅烷中，聚硅三亚甲基是基本的。它们可以容易地由容易获得或市售的硅杂环丁烷3制备。由于环张力，它们具有相对高的反应性。虽然对1，1-二甲基硅环丁烷（1）的阴离子、热、过渡金属催化开环聚合作了大量的工作，但还没有研究
Revised Manuscript Received July 25, 1995 Introduction. Polycarbosilanes have recently at-tracted much attention because of their uniquecharac-teristics compared to the usual hydrocarbon polymers. 1’2 The development of synthetic methods to obtain well-defined polycarbosilanes is indispensable for the de-tailed investigations of the chemical andphysical properties of polycarbosilanes and their application to functional materials.Among many kinds of polycarbosilanes, polysiltri-methylenes are fundamental. They can be readily prepared from silacyclobutanes, 3 which are easily ac-cessible or commercially available. They have relatively high reactivities due to ring strain. Although consider-able work has been done on the anionic, 4 thermal, 5 and transition-metal-catalyzed6 ring-opening polymerization of 1, 1-dimethylsilacyclobutane (1), no study has been
