Abstract (en)

[origin: WO9910398A2] The invention concerns 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, thereby forming a condensation polymer/first polymer matrix.
