Abstract:
A method of making a condensation polymer/silicone polymer blend comprising the steps of:a. preparing a silicone polymer emulsion comprising i) a silicone polymer; ii) a surfactant; and iii) a liquid continuous phase comprising a diol, wherein the diol comprises from about 25 to about 100% by weight of the continuous phase; b. introducing the silicone polymer emulsion into a condensation polymerization reaction medium prior to or during the condensation polymerization reaction, wherein the condensation polymerization reaction medium comprises (1) a diacid, di-isocyanate, dialkyl carbonate, diaryl carbonate, dihalo carbonate or a mixture thereof, wherein the condensation polymerization reaction medium may comprise a diol component; and c. polymerizing the diol and component b(1) thereby forming a condensation polymer/silicone polymer blend.
