| titleOfInvention | Graft copolymers of certain monomeric sulfonic acids |
| abstract | Graft copolymers are prepared by polymerizing between 10% and 80% by weight, based on the resulting graft copolymer, of an alkenyl group-containing organic sulphonic acid and between 90% and 20% of (1) an N-vinyl-3-morpholinone polymer or (2) a copolymer of an N-vinyl-2-oxazolidinone (10% to 90%) and an N-vinyl lactam (90 to 10%), e.g. N-vinyl pyrrolidones, N-vinyl caprolactam and N-vinyl piperidone. The N-vinyl-3-morpholinone polymer used may be a homopolymer or a copolymer with a substituted N-vinyl morpholinone, a vinyl lactam or a vinyl oxazolidinone. Sulphonic monomers specified are the sodium salts of styrene sulphonic acid, ethylene sulphonic acid, allyl taurine, acryloyl taurine, and sulphoethyl acrylate and methacrylate. The resulting graft copolymers may be used as additives to acrylonitrile polymers in the manner described in the parent Specification, e.g. by passing polyacrylonitrile fibres in aquagel form through an impregnating bath containing dissolved graft copolymer. |
