ANTIMICROBIAL POLYMERIC COMPOSITIONS

摘要

A METHOD FOR IMPROVING THE ANTIMICROBIAL ACTIVITY OF A POLYMER DERIVED FROM ACROLEIN MONOMER WHEREIN THE POLYMER HAS BEEN OXIDIZED IN AIR TO FORM AN OXIDISED ACROLEIN POLYMER COMPRISING CARBOXYL GROUPS, SAID METHOD COMPRISING : @PROVIDING A SOLUTION OF THE OXIDIZED ACROLEIN POLYMER COMPRISING CARBOXYL GROUPS IN A MIXTURE CONTAINING WATER AND A HYDROXYLIC SOLVENT INCLUDING AN ALCOHOL SELECTED FROM THE GROUP CONSISTING OF POLYOLS, POLYETHYLENE GLYCOLS AND ALKANOLS; AND@HEATING THE SOLUTION AT A TEMPERATURE IN THE RANGE OF FROM 40 TO 150°C FOR A PERIOD SUFFICIENT TO IMPROVE THE ANTIMICROBIAL ACTIVITY OF THE ACROLEIN POLYMER.
