Antimicrobial polymeric compositions

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 deg.C. Further, the polymers may be prepared in the presence of polyethylene glycols, polyols and / or alkanols.

Description

technical field

[0001] The present invention relates to antimicrobial polymer compositions. More specifically, the antimicrobial polymer compositions of the present invention contain compounds having polyacrylaldehyde subunits with aldehyde groups in free form, hydrated form, hemiacetal form or acetal form and which have bioinhibitory properties and / or insecticidal properties. The invention also relates to compositions containing these polymeric compounds and to the biostatic and / or insecticidal applications of these compositions. Background technique

[0002] Has been shown in the past to contain the following repeating polymer units or polymers of units in hydrated form, hemiacetal form or acetal form (hereinafter referred to as "the subject polymer") having broad-spectrum antimicrobial properties, In the formula, R is hydrogen or an alkyl group, and n is an integer of 1 or more (Nelrose et al., International Patent WO88 / 04671). The subject polymers disclosed herein ...
