Abstract
The possibility of an inter facial polycondensation of 1,3-bis(hydroxymethyl)-1,3-bis(γ-hydroxypropyl)- and 1,3-bis(γ-o-hydroxyphenylpropyl)-1,1,3,3-tetramethyl-disiloxanes with COCl2 is reported here for the first time, and some of the process mechanisms have been investigated. The produced polysiloxane carbonates have been found to have Mn values between 1000 and 500, to be heat resistant in air up to 250–300°C.
