Claims29
The process for the production of copolymer of allyl monohalide and organic polymerizable unsaturated compounds by the following steps:
- (a) mixing a material consisting of a fine granular oxidated silicon compound wherein the oxidated silicon compound is selected from the group consisting of hydrated silica, silica, silicoformic acid, polysilicoformic acid, naturally occurring silicates with free silicic acid groups and mixtures thereof, with 1 to 3 parts by weight of an allyl mono-halide;
- (b) adding 0.10 to 5 parts by weight of an organic polymerizable unsaturated compound to each part by weight of the allylmono-halide compound;
- (c) agitating the mixture at a temperature between the temperature at which the polymerizable organic compound is in the liquid state and the lowest boiling temperature of the reactants, and at ambient to 60 psig, for 1 to 12 hours, thereby
- (d) producing a copolymer.
