Abstract

The present invention provides grafted polymers that have pendent functional groups on the core of the polymer wherein the core is a polymerized alkylmethacrylate having a number average molecular weight from 500 to 1,000,000. The arms of the grafted polymer comprise anionically polymerized segments that have number average molecular weights from 1,000 to 300,000.
