Abstract
Poly(amine allyl halides) copolymer may be produced by mixing an amine compound and a mono-olefinic allyl type monohalide compound in the presence of an oxidized silicon catalyst.
Claims7
The process for the production of poly(allylhalide amine) copolymer by the following steps:
- (a) admixing an allyl halide and an amine compound in the ratio of 1 mol of the amine to 0.5 to 6 mols of the allyl halide with an oxidated silicon compound in the ratio of 1 part by weight of the oxidated silicon compound to 1 to 3 parts by weight of the allyl halide;
- (b) agitating said mixture for 10 to 60 minutes as a temperature between ambient temperature and the boiling point of the reactants, thereby
- (c) producing a poly(allylhalide amine) copolymer.
