ORGANO SILYLETHYLENEDIAMINE COMPOUNDS Ⅲ:Structural Investigation on Organosilylethylenediamine Polymers

摘要

The polymers which are formed by the reaction of ethylenediamine and dimethyldichlorosilane are investigated by NMR methods. These polymers consist of a mixture of linear and cyclic units in a ratio of about 1:2. By heating the polymers to about 300 of by reaction with Me3SiCl polymers of the pure cyclic species are obtained. By reaction with ethylene diamine polymers with a higher ratio of the linear component are formed. A pure linear polymer even by reaction with an excess of ethylene diamine.
