Title:
DIOL LATEX COMPOSITIONS AND MODIFIED CONDENSATION POLYMERS
Document Type and Number:
WIPO Patent Application WO2000052082
Kind Code:
A3
Abstract:
In a first aspect, the invention provides a diol latex composition comprising: (a) latex polymer particles comprising a residue of an ethylenically unsaturated monomer, wherein the latex polymer particles have a size below 1000 nm; (b) a surfactant; and (c) a continuous liquid phase comprising a diol component, wherein the diol component comprises from 60 to 100 % by weight of the continuous phase, wherein the latex polymer particles are dispersed in the continuous phase. In a next aspect, the invention provides a method of making a condensation polymer/first polymer matrix comprising the steps of: (a) preparing a polymer colloid system comprising a first polymer dispersed in a liquid continuous phase; and (b) introducing the polymer colloid system into a condensation reaction medium prior to or during the condensation reaction, wherein the condensation reaction medium comprises (1) a diacid, di-isocyanate, dialkyl carbonate, diaryl carbonate, dihalo carbonate or a mixture thereof, wherein the liquid continuous phase, the condensation reaction medium or both comprises a diol component; and (c) polymerizing the diol component and component b(1), thereby forming a condensation polymer/first polymer matrix.
