Title:

POLYAMIDE 1010 RESIN PARTICLES AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2013/046860

Kind Code:

A1

Abstract:

The production of polyamide 1010 resin particles, in which polyamide 1010 resin, a different polymer (B), and an organic solvent are dissolved and mixed and thereupon an emulsion is formed within a system for phase-separation into two phases, being a solution phase having the polyamide 1010 resin as the main component and a solution phase having the polymer (B) as the main component, and thereafter a poor solvent of the polyamide 1010 resin is brought into contact therewith to precipitate the polyamide 1010 resin, wherein the formation of the emulsion is implemented at a temperature of 100°C or greater, thereby making it possible to obtain highly crystalline polyamide 1010 particles having high sphericity.
