Abstract

Abstract A dithiocarbamate group-containing polysiloxane represented by the following general formula (I): ##STR1## wherein X 1 , X 2 and X 3 each stand for: (a) a dithiocarbamate-containing group represented by the formula: ##STR2## wherein R 8 and R 9 each denote a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, and R 10 stands for a benzyl-containing group ##STR3## with a being a natural number of 1 to 10 or an alkylene group having 1 to 10 carbon atoms, (b) a dithiocarbamate group represented by the formula: ##STR4## wherein R 11 and R 12 each denote a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, (c) a hydrocarbyl or hydrocarbyloxy group having 1 to 10 carbon atoms, (d) a fluoroalkyl group having 1 to 10 carbon atoms and 1 to 17 fluorine atoms, or (e) a hydroxyl group; provided that at least one of X 1 , X 2 and X 3 is the dithiocarbamate-containing group (a) or the dithiocarbamate group (b); and R 1 to R 7 each stand for: (f) a hydrocarbyl or hydrocarbyloxy group having 1 to 10 carbon atoms, (g) a fluoroalkyl group having 1 to 10 carbon atoms and 1 to 17 fluorine atoms, or (h) a hydroxyl group; and n is a natural number of 1 to 10 and m is a natural number of 20 to 800.
