1. A process for reducing the crystallization temperature and the melting temperature of a polyamide powder derived from the polymerization of at least one major monomer, said process comprising polymerization of said at least one major monomer with at least one different minor comonomer polymerized according to the same polymerization process as said at least one major monomer, said at least one minor comonomer representing from 0.1% to 20% by mass of the total blend of said monomer(s) and comonomer(s), 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 at least one major monomer alone,
wherein the change in the crystallization temperature is at least 3° C.
