Abstract:
A method of making a condensation polymer/latex polymer blend comprising the steps of:(a) preparing a latex composition comprising: i) a sulfo-polyester polymer; and ii) a latex polymer dispersed in a liquid continuous phase; (b) introducing the latex composition into a condensation polymerization reaction medium prior to or during a condensation polymerization reaction, wherein the condensation polymerization reaction medium comprises (1) a diacid, diisocyanate, dialkyl carbonate, esters, diaryl carbonate, dihalo carbonate or a mixture thereof, wherein at least one of the liquid continuous phase, the condensation polymerization reaction medium, or the sulfo-polyester polymer comprises a diol component; and (c) polymerizing the diol component and component b(l), thereby forming a condensation polymer/latex polymer blend.
