Method for preparing condensation polymers by emulsion polymerization
摘要:
Polyesters are prepared by reacting aqueous compositions containing an emulsified hydroxyacid or an emulsified mixture comprising a polyfunctional carboxylic acid or anhydride and a polyfunctional alcohol. The emulsion also contains a suitable polycondensation catalyst. The resultant polyesters are useful as plasticizers and as precursors for alkyd resins and other polymers.
