Life of this patent

Estimating the term…

Allyl halides are polymerized by alkali metal silicates and alkaline earth metal silicates to produce poly (allyl halide allyl alcohol) polymers.

Dependent claims

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.

Dependencies are inferred from the claim text.
