Abstract
Small particles of cellulose-containing plants are mixed with an alkali metal hydroxide and an oxidated silicon compound, then heated to 150.degree. C. to 220.degree. C. while agitating, thereby producing a broken-down lignin-cellulose silicate polymer which is then reacted with a substituted organic compound to produce an organic broken-down lignin-cellulose silicate polymer and may be used as molding powder and as a coating agent.
Claims9
The process for the production of broken-down organic lignin-cellulose silicate polymer by mixing and reacting the following components:
- Component (a):
- Broken-down alkali metal lignin-cellulose silicate polymer;
- Component (b):
- A substituted organic compound having a substituent which will split off during the reaction, to said broken-down alkali metal lignin-cellulose polymer in the amount wherein the mols of the substituted radicals are about equal to the mols of the alkali radicals in the mixture.
