Summary
-
1.
The IR absorption spectra of a series of 1,1-substituted silicacyclobutanes, silicacyclopentanes, and the corresponding polymers were obtained and investigated.
-
2.
The frequencies characterizing the 1,1-substituted silicacyclobutane and silicacyclopentane rings were established.
-
3.
As a result of an investigation of the IR spectra of the polymers produced by thermal polymerization of a number of 1,1-substituted silicacyclobutanes, it was established that the polymerization products are heterochain polymers with the structural fragment
as the unit of the basic chain.
-
4.
In the catalytic polymerization of 1,1-substituted silicacyclopentanes, heterochain polymers are formed, with the structural fragment
as the unit of the basic chain.
