## Abstract

What is provided herein are active antimicrobial polymeric quaternary ammonium compounds which are capped with defined C.sub.12 /C.sub.14 alkyl groups optionally coprecipitated with polyvinylpyrrolidone (PVP). The compounds of the invention have the formula: ##STR1## where n is at least 2, e.g. 2-30, and C.sub.12 /C.sub.14 alkyl preferably is 50:50 wt. % of dodecyl/tetradecyl alkyl.

## Claims

### Claim 1

Antimicrobial polymeric quaternary ammonium compounds having the formula: ##STR5## where Y is alkylene interrupted with oxygen, X is selected from chlorine and bromine, and
n is 2-30.

### Claim 2 (depends on 1)

Antimicrobial polymeric quaternary ammonium compounds according to claim 1 where C.sub.12 /C.sub.14 alkyl is a 50:50 mixture of the alkyl groups.

### Claim 3 (depends on 1)

Antimicrobial polymeric quaternary compounds according to claim 1 where X is chlorine.

### Claim 4 (depends on 1)

Antimicrobial polymeric quaternary compounds according to claim 1 which have the formula ##STR6##
