PCT No. PCT/EP93/00609 Sec. 371 Date Sep. 9, 1994 Sec. 102(e) Date Sep. 9, 1994 PCT Filed Mar. 16, 1993 PCT Pub. No. WO93/19231 PCT Pub. Date Sep. 30, 1993A fiber predominantly composed of polyethylene terephthalate as fiber polymer, which contains 0.1 to 5% by weight, based on the fiber polymer, of a polyalkyl methacrylate, imidated up to 50 to 90%, predominantly in the form of inclusions. Also provided is a process for the production of melt-spun fibers, essentially composed of polyethylene terephthalate, by melting the fiber polymer and subsequent melt spinning, characterized in that the fiber polymer receives an admixture of 0.1 to 5% by weight, based on the fiber polymer, of a polymer only partially soluble in this and essentially composed of imidated polyalkyl methacrylates which are imidated up to 50 to 90% by reaction of polyalkyl methacrylates, the ester group of which contains an alcohol having 1 to 6 C atoms, with a primary amine having 1 to 3 C atoms, and the acid and/or anhydride content of which is less than 0.25 milliequivalents per gram and, possibly, other additives prior to the melt spinning. |
