| Abstract: | The cohydrolysis of γ-trifluoropropenylmethyldichlorosilane and dimethyldichlorosilane at 70°–75° C leads to the formation of γ-trifluoropropenylnonamethylcyclopentasiloxane, γ-trifluoropropenyl-pentamethylcyclotrisiloxane, and bis(γ-trifluoropropenyl)hexamethylcyclotetrasiloxane. These oligomers were polymerized in the presence of a Ziegler-Natta catalyst, forming low-molecular-weight oily polymers with M = 1000–3000. |
