Surface-active macromonomers
 A new class of polymerizable surfactants, useful for modifying the surfaces of polymeric objects, which are described by the formula: EQU DC[A.sub.x B.sub.y ] wherein A is at least one ethylenically unsaturated hydrophilic monomer, B is at least one ethylenically unsaturated hydrophobic monomer, C is a functional chain transfer agent, D is an ethylenically unsaturated end group, y is within the range from about 0.1 to about 0.9, and x+y=1. Also disclosed are random copolymer precursors of such polymerizable surfactants.
