| Abstract: | Preparation of polycarbosilane (PCS) by pyrolysis of polydimethylsilane has been investigated. Effect of synthesis condition on the properties of products was studied. Molecular weight and melting point of products increase with increasing reaction temperature, but the dispersity of molecular weight increases at the same time, which results in the degradation of spinnability of PCS. PCS with desired properties has been obtained by using suitable preparation method. |
