Abstract
Polymers, such as ethylene-vinylacetate copolymer, polyvinyl alcohol or cellulose, containing amine groups or salts thereof or quaternary ammonium groups are disclosed. The polymers can be processed easily and display other interesting chemical properties such as having the particular chemical properties of the functional groups they contain. These polymers are prepared, generally by reacting a hydroxyl-containing polymer with a reactive compound which contains an available amine group.
