摘要
The invention relates to partially crosslinked organopolysiloxanes which are soluble in organic solvents and contain free-radical-forming groups, built up from units of the formula [RaSi(O(3-a)/2)-R1-X-R1-Si(O(3-a)/2)Ra] (1) where X is a radical from the group consisting of -N=N-, -O-O-, -S-S- and -C(C6H5)2-C(C6H5)2-, and R, R1, R2, a and b are as defined in Claim 1, and further organosiloxane units. The organopolysiloxanes are used as free-radical macroinitiators for the graft copolymerisation of ethylenically unsaturated monomers.
