1. A method of producing a polymeric object, the method comprising sequential steps of:
heating an organic solvent that comprises a halogen-containing polymer and an aliphatic amino alcohol of general formula HO(CH2)mNH2 where m is an integer from 1-10, thereby producing a first polymer with first hydroxyl groups;
transforming the first hydroxyl groups to leaving groups;
adding an amine under conditions that displace the leaving groups and covalently link the amine to the halogen-containing polymer, thereby producing a halogen-containing polymer with quaternary ammonium salts covalently linked thereto;
producing the polymeric object from the halogen-containing polymer.
