Abstract

The present polysilethylenesiloxane is a liquid polymer represented by the following general formula: ##STR1## wherein R.sup.1 and R.sup.2 each represent a lower alkyl group and R.sup.3 and R.sup.4 each represent a perfluoroalkylethyl group, and n is an integer of 10 to 1,000. This polymer is quite useful as a major component of elastomer compositions having chemical resistance, electrical properties, and high strength.
