ABSTRACT:
A novel polyorganosiloxane is provided which has a fluorine atom-containing substituent at one terminal of its molecular chain and an unsaturated double bond-containing substituent at the other terminal thereof. The polyorgansiloxane of the present invention is represented by the general formula (I) ##STR1## wherein j is an integer of 1 to 2000, and R.sup.1 is an unsaturated double bond-containing group, each of R.sup.2 and R.sup.3 is an alkyl group having 1 to 4 carbon atoms, phenyl group, vinyl group, straight-chain or branched alkenyl group having 3 to 20 carbon atoms, or a siloxane chain which is similar to ##STR2## and R.sup.4 is a fluorine atom-containing substituent, ##STR3## wherein R.sup.10 is similar to R.sup.4 and is the fruorine atom-containing substituent, R.sup.11 is an alkyl group having 1 to 4 carbon atoms or phenyl group, and the oxygen atoms sited on the right side of the above formulae are combined with a siloxane chain having the unsaturated double bond-containing substituent at the terminal thereof which is similar to ##STR4##
