LPS, which is used as feed stock to synthesize PCS under normal pressure at high temperature, is composed of the backbone structure of polysilane (Si-Si) and PCS (Si-C). Active group Si-H in the chain can easily react with double bonds by hydrosilication.

• 高温常压法合成PCS的原料LPS含有聚硅烷(Si-Si)与聚碳硅烷(Si-C)的主链结构,链中活泼的Si-H基团与烯键容易发生硅氢化反应。
