Summary:A series of poly[dimethyl(methylbenzyl)siloxanes] with different content of the methylbenzylsiloxane fragments have been synthesized. Structure of the polymers has been confirmed by means of 1 Н and 29 Si NMR spectroscopy. Thermal properties of the polymers have been investigated by means of differential scanning calorimetry and thermogravimetric analysis. It has been found that the copolymer crystallization is suppressed at the content of the methylbenzylsiloxane fragments on the copolymer of 3 mol % and higher, while the glass transition temperature is only insignificantly shifted towards the positive range. The copolymers have exhibited high temperature resistance and can be used over a wide temperature range.
