Abstract
The invention provides a method of making an amide-type polymer/first polymer blend comprising the steps of: a) preparing a polymer colloid system comprising a first polymer dispersed in a liquid continuous phase; b) introducing the polymer colloid system into an amide-type polymerization reaction medium prior to or during the reaction, wherein the reaction medium comprises 1) a diacid component and a diamine component, an oligomer of a diacid and a diamine component, or a mixture thereof; and c) polymerizing the components of b)1, thereby providing an amide-type polymer/first polymer blend. Polymer blends made by the methods herein are also provided.
