Abstract:
The present invention relates to a method for reducing the crystallization temperature an the melting temperature of a polyamide powder resulting from the polymerization of at least one predominant monomer, in which the reduction in the crystallization temperature is greater than the reduction in the melting temperature, said method comprising a step of polymerization of said at least one predominant monomer with at least one different minor comonomer polymerized according to the same polymerization process as said at least one predominant monomer, said at least one minor comonomer being chosen from aminocarboxylic acids, diamine/diacid pairs, lactams and/or lactones, and said at least one minor comonomer representing from 0.1% to 20% by weight of the total blend of said monomers(s) and comonomer(s), preferably from 0.5% to 15% by weight of said total blend, preferably from 1% to 10% by weight of said total blend.

Claim (Index 18):
A process for reducing the crystallization temperature and the melting temperature of a polyamide derived from the polymerization of only one major monomer, said process comprising:\n polymerization of said only one major monomer with only one different minor comonomer polymerized according to the same polymerization process as said only one major monomer, said only one minor comonomer selected from the group consisting of 11-aminoundecanoic acid, lauryllactam, caprolactam, caprolactone, and a diamine-diacid selected from the group consisting of: 6.6, 6.10, 6.11, 6.12, 6.14, 6.18, 10.10, 10.12, 10.14, 10.18 and 10.T, T being terephthalic acid, minor comonomer representing from 1% to 7% by mass of the total blend of said monomer and comonomer, such that the reduction in the crystallization temperature is greater than the reduction in the melting temperature, relative to the crystallization temperature and the melting temperature of the polyamide obtained from the polymerization of said major monomer, wherein the polyamide obtained from the polymerization of said major monomer is a powder with a particles size of 10 \u03bcm to 350 \u03bcm, and wherein the major monomer is selected from the group consisting of 11-aminoundecanoic acid, lactam 12, and decanediamine-sebacic acid couple (10.10).
