Abstract
Small particles of lignin-cellulose-containing plants are mixed with an alkali metal silicate, then heated at 80.degree. C. to 120.degree. C. while agitating, thereby producing an alkali metal lignin-cellulose silicate polymer.

The process for the production of alkali metal lignin-cellulose silicate polymer by mixing and reacting the following:
- (A) 2 parts by weight of alkali metal silicate;
- (B) 1 to 3 parts by weight of lignin-cellulose containing plant;
- the reaction is carried out by heating the mixture at 80.degree. C. to 120.degree. C. while agitating at ambient pressure for 10 to 60 minutes.
