Abstract
Allyl halides are polymerized by a catalyst, silicic or silicoformic acids, to produce poly(allyl halide) polymer and poly(allyl alcohol) polymer.
Claims4
The process for the production of poly(allyl silicoformate) polymer by the following steps:
- (a) mixing 1 part by weight of an alkali compound, 1 part by weight of a silicon acid and 2 parts by weight of an allyl halide;
- (b) heating said mixture to 30.degree. to 40.degree. C. while agitating for 20 to 40 minutes under ambient pressure, thereby
- (c) producing poly(allyl silicoformate) polymer and salt;
- (d) washing said mixture of poly(allyl silicoformate) polymer and salt with water, then filtering off the salt and water, thereby
- (e) recovering poly(allyl silicoformate) polymer.
