Abstract

Diverse mercerized celluloses (powder cellulose and kraft pulp) have been successfully vinylated with acetylene in an aqueous solution of alkali metal hydroxides (KOH or NaOH) at 125–140 °C. Depending on the reaction conditions, degree of substitution (DS) of the hydroxyl groups by highly reactive polymerazable vinyloxy groups ranges 0.08–0.73, the yields of vinyl celluloses being 24–75%. The process is accompanied by alkaline degradation of the cellulose macromolecule.
