Polyurethane-modified organopolysiloxan compositions, process for preparing same and their application

摘要

The present invention relates to polysiloxanes modified with polyurethane, which are characterized in that polysiloxane and polyurethane are present as distinguishable phases, optionally with a partial chemical and / or physical bond to one another. The organopolysiloxane compositions filled with polyurethane are produced by intensively mixing the organopolysiloxane liquid with a diol or polyol and then adding a diisocyanate to this mixture. The mixtures can contain from about 3 to 95% by weight of polyurethane, based on the total mixture.
