Abstract: Amphiphilic graft copolymers are prepared by grafting a pre-formed graft base polymer comprising at least 5% by weight of units of formula (I)where R1 and R2 are independently H or C1 to C6 alkyl groups. The monomer grafted to the pre-formed graft base polymer is at least one of styrene or a C1 to C2 alkylstyrene, and optionally other monoethylenically unsaturated monomers. At least 5 mole % of the groupsare cleaved from the grafted copolymer thus formed.
