Abstract:
An antimicrobial agent comprising a non-cross-linked polymer comprising a resin selected from the Group consisting of an ester resin, an amide resin, and an ester and amide resin, having a quaternary ammonium salt bonded thereto by a covalent bond which is potentially reactive with water, the quaternary ammonium salt being present in an amount of at least 1 mole/kg, and being at least one compound selected from the group consisting of:a) a compound of the formula ##STR13##where R.sup.1 is a C.sub.1 -C.sub.5 alkyl chain, R.sub.2 is a C.sub.1 -C.sub.5 alkyl chain, R.sub.3 is a C.sub.8 -C.sub.20 alkyl chain or an aryl or arylalkyl group, and X is an anion; andb) a compound of formula W.sup.+ X.sup.-, where W.sup.+ is a saturated or unsaturated heterocycle comprising a quaternized nitrogen atom substituted with a substituent R.sub.4 or directly bonded to the polymer, where R.sub.4 is a C.sub.1 -C.sub.20 alkyl chain or an aryl or alkylaryl group, and X.sup.- is an anion.
