NEUTRALIZING AGENTS FOR RESIN EMULSIONS

摘要

Incorporation of organic amines as neutralization agents in based phase inversion emulsification (PIE) processes to provide emulsification of high molecular amorphous and high molecular branch amorphous polyester resins, which are traditionally difficult to emulsify. The organic amines facilitate emulsification of these resins to achieve desired particle size with a narrow size distribution.

1. A process comprising:
mixing at least one polyester resin with a solvent to form a resin mixture; neutralizing the resin mixture with a neutralizing agent in water; and agitating the resin mixture and neutralizing agent in water to form an aqueous emulsion, wherein the neutralizing agent is an organic amine.
