Abstract
Allyl halides are polymerized by a catalyst, silicic or silicoformic acids, to produce poly(allyl halide) polymer and poly(allyl alcohol) polymer.
Claims5
The process for the production of poly(allyl silicoformate) by the following steps:
- a. providing a quantity of silicon acid;
- b. mixing 1 part by weight of granular silicon acid with 2 parts by weight of an allyl halide;
- c. agitating said mixture in a closed system and keeping the temperature between 0.degree. to 100.degree. C for about 20 to 40 minutes at ambient pressure;
- thereby
- d. producing poly(allyl halide) polymer;
- e. adding 1 part by weight of sodium carbonate to the mixture of silicon acid and poly(allyl halide) polymer;
- f. heating said mixture to 60.degree. to 80.degree. C while agitating for 20 to 40 minutes under ambient pressure, thereby
- g. producing poly(allyl silicoformate) polymer and salt;
- h. washing said mixture with water;
- i. filtering off the salt and water, thereby
- j. recovering poly(allyl silicoformate) polymer.
