WATER-SOLUBLE POLYMERS CARRYING QUATERNARY AMMONIUM GROUPS, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF

摘要

A water soluble polymer having quaternary ammonium groups is disclosed together with a method for its production and an impregnating agent for wood and wood products containing the polymer. The method of the invention comprises building up a 1,3-butadiene polymer, epoxidating the polymer, reacting the epoxidated product with diamines and reacting the aminated product with a low molecular weight oxiran. The polymers of the invention provide bonding agents with the improved ability of absorbing inorganic salts and acids that act as protecting agents for the wood.
