Abstract
The present invention relates to a series of novel imidazolinium quaternary polymers. The compounds of the present invent ion are prepared by the reaction of chloracetic acid with a pendant hydroxyl group which is present on a polyoxyalkylene polymer, followed by the reaction of the halo-ester with a tertiary amine to give a quaternary compound. In a preferred embodiment the polyoxyalkylene glycol has been prepared by the reaction of both ethylene oxide and propylene oxide. In a more preferred embodiment, the ethylene oxide is at the terminal portion of the molecule and the propylene oxide is in the center.
