ABSTRACT:
Polymeric quaternary ammonium compounds having recurring vinylbenzyl ammonium units are disclosed. The quaternary ammonium units preferably have 2 alkyl substituents of 1 to 4 carbons and 1 alkyl substituent of 4 to 12 carbons. These materials have antimicrobial properties and are particularly useful for preserving ophthalmic solutions.
