Abstract
A method for the preparation of polymers derived from acrolein and including poly(2-propenal, 2-propenoic acid), characterised in that the polymers are exposed to the presence of water, whereby such polymers exhibit increased antimicrobial activity. The polymers may be heated in the range of 40 to 150° C. Further, the polymers may be prepared in the presence of polyethylene glycols, polyols and/or alkanols.
Claims19
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 oxidized 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 solvent comprising 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.
