Title:
POLYAMIDE PARTICLES, AND METHOD FOR PRODUCING POLYAMIDE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/150835
Kind Code:
A1
Abstract:
Provided are non-spherical polyamide particles having a small variation in particle shapes. The polyamide particles are made from a polyamide which is composed of repeated structural units each having at least one alkylene group and at least one amide bond, wherein the at least one alkylene group has 1 to 3 carbon atoms inclusive, the main shape of the individual particles is a non-spherical shape having a circularity degree of less than 0.98 and the coefficient of variation (CV) of the circularity degree distribution is 30% or less.
