Abstract: Concentrates of from 20 to 50% by weight of titanium dioxide in polycaprolactam are produced by a process in which a 5-15% strength by weight aqueous suspension of titanium dioxide is metered into a solution of caprolactam in water at from 100 DEG to 150 DEG C. at the same rate at which water is distilled off, and after the water has been distilled off the resulting mixture is polymerized at from 240 DEG to 280 DEG C.

Abstract: An improved process for the preparation of fiber-forming polycaprolactam by polymerizing epsilon -caprolactam, and an aqueous extract containing epsilon -caprolactam and caprolactam oligomers, which extract has been obtained by extracting polycaprolactam with water, wherein the aqueous extract contains from 0.1 to 5.0% by weight of oligomers of caprolactam, based on the monomeric caprolactam in the aqueous extract.
