摘要

The composition which predominantly consists of heat-curable, polyol-modified polysiloxane A and. based on polysiloxane A, 0.05 to 4% by weight of a linear siloxane B which is reactive with said siloxane A, the modified polysiloxane A being obtainable by reacting a polysiloxane A1 of the general formula …IMAGE… (OR1 = alkoxy group derived from primary or secondary alcohol having 1 to 4 carbon atoms,… R2 = alkyl and/or phenyl radical,… a = 1 to 1.5,… b = 0.1 to 0.3… with a polyhydric alcohol A2, characterised in that the polyhydric alcohol A2 used is a polyol containing ester groups and of the general formula …IMAGE… obtainable by esterifying 1 mol of a dicarboxylic acid HOOC-R7-COOH with 2 mol of an alcohol of the formula R6OH, in which the R6 radicals in the molecule are identical or different and denote the group …IMAGE… in which R7 is an alkylene, cycloalkylene or phenylene group, and the polyol containing ester groups must have at least three hydroxyl groups.
