    Abstract: 1362044 Poly-N-vinyl pyrrolidone-2 BADISCHE ANILIN- & SODA-FABRIK AG 2 Dec 1971 [3 Dec 1970] 55929/71 Heading C3P] [Also in Division C6] An insoluble and only slightly swellable poly- N-vinyl pyrrolidone-2 is prepared by polymerizing N-vinyl pyrrolidone-2 in aqueous solution in the presence of 0À5 to 10% by weight, based on the N-vinyl pyrrolidone, of a cyclic acid amide containing at least two ethylenically unsaturated groups, one of which is attached to an amide nitrogen atom which forms part of a heterocyclic ring, the polymerization being started at the surface of a metal which is susceptible to attack by oxygen and which is capable of forming a permeable oxide film or by seeds of poly-N-vinyl pyrrolidone-2 formed at the surface of said metal. The metal may be Fe, an Fe alloy, Co, Zn or Sn and may be the reactor. The amide may be N,N 1 - divinylimidazolidone - 2, N,N 1 - divinylhexahydropyrimidinone-2 or N-vinyl-3-ethylidinepyrrolidone-2. In the examples, N-vinylpyrrolidone-2 is polymerized in the presence of N,N 1 - divinylimidazolidone - 2, dibenzoyl peroxide and iron or zinc or seeds are produced by polymerizing N-vinylpyrrolidone-2 in the presence of N,N 1 -divinyl imidazolidone-2 or N,N 1 - divinylhexahydropyrimidone-2 dibenzoyl peroxide and iron and the seeds are used to polymerize N-vinyl pyrrolidone-2 in the presence of N,N 1 -divinyl imidazolidone-2 or N,N 1 -divinylhexahydropyrimidone-2.
