  • Soluble organopolysiloxane free-radical macroinitators for graft copolymerization
    Patent number: 5605983
    Abstract: The invention relates to partially crosslinked organopolysiloxanes which contain a radical forming group, a base-catalyzed process for their preparation, graft copolymers produced from these organopolysiloxanes and a process for the preparation of the graft copolymers. The present invention avoids problems related to known methods wherein a considerable portion of the organopolymer chains do not graft to the organopolysiloxane graft back-bone but remain as an unattached homopolymers.
