Claims
- 1. The process for the production of poly (allyl halide allyl alcohol) polymer by the following steps:
- (a) mixing about one part by weight of an alkali silicate with about 1 to 2 parts by weight of a mono-olefinic allyl type mono-halide;
- (b) agitating said mixture in a closed system and keeping the temperature between 0.degree. and 100.degree. C. for about 1 to 12 hours at ambient pressure, thereby
- (c) producing poly (allyl halide allyl alcohol) polymer.
- 2. The process according to claim 1, wherein the alkali silicate is selected from the group consisting of alkali metal silicates, alkaline earth metal silicates and natural occurring alkali silicates with free silicic acid radicals and mixtures thereof.
- 3. The process according to claim 1, wherein the mono-olefinic allyl type mono-halides with the essential grouping of atoms may be represented as ##STR2## wherein R is a hydrogen or a C.sub.1 to C.sub.4 alkyl group wherein X represents a halogen atom.
- 4. The process according to claim 1, wherein the mono-olefinic allyl type mono-halide is selected from the group consisting of allyl chloride, allyl bromide, crotyl chloride, crotyl iodide, beta-methylallyl chloride, beta-methylallyl bromide, methyl vinyl carbinyl chloride, methyl vinyl carbinyl fluoride, alpha-dimethylallyl chloride, beta-cyclohexylallyl chloride, cinnamyl chloride, beta-ethylcrotyl chloride, beta-phenylallyl bromide, alpha-dicyclohexylallyl chloride, beta-propylallyl iodine, beta-phenylallyl chloride, beta-cyclohexylallyl fluoride, 2-chloromethyl butene-1, 2-chloromethyl pentene-1, 2-chloromethyl hexene-1 and mixtures thereof.
- 5. The process according to claim 1, wherein the mono-olefinic allyl type mono-halide is selected from the group consisting of allyl chloride, allyl bromide, methylallyl chloride and mixtures thereof.
- 6. The process according to claim 1, wherein 1 part by weight of allyl alcohol is added in step (a) of claim 1, thereby producing poly (allyl halide allyl alcohol) co-polymer.
- 7. The process according to claim 1, wherein 1% to 10% by weight of a fine granular hydrated silica, percentage based on the weight of the reactants, is added in step (a) of claim 1.
- 8. The process according to claim 1, wherein additional steps are added following step (c) of claim 1;
- (d) adding one part by weight of an alkali metal hydroxide, selected from sodium hydroxide and potassium hydroxide, in water to the said poly (allyl halide allyl alcohol) polymer.
- (e) agitating while heating to 70.degree. to 100.degree. C. for 20 to 60 minutes, thereby
- (f) producing a poly (allyl alcohol) polymer, alkali metal salt and alkali silicate.
- (g) recovering the poly (allyl alcohol) by letting the said polymer float to the top of the water, then decanting off the water, alkali halide and alkali silicate.
- 9. The process according to claim 1, wherein additional steps are added following step (c) of claim 1;
- (d) heating the mixture of alkali silicate, alkali halide and poly (allyl halide allyl alcohol) polymer to 70.degree. to 120.degree. C. while agitating at ambient pressure for 20 to 60 minutes, thereby producing poly (allyl silicate allyl alcohol) polymer.
- 10. The product, poly (allyl silicate allyl alcohol) polymer, as produced by the process of claim 9.
