ABSTRACT:
Small particles of cellulose-containing plants are mixed with an alkali metal hydroxide then heated to 150.degree. to 220.degree. C. while agitating thereby producing a broken down cellulose polymer which is then reacted with a polysubstituted organic compound in an aqueous solution to produce a broken down cellulose copolymer.
