1. A process for modifying the surface of a silicon-containing polymer, the process comprising the steps of:
- forming a reaction mixture comprising the silicon-containing polymer, a polymerization monomer, a free radical redox initiator system and a solvent system, the polymerization monomer comprising a zwitterionic monomer and the free radical redox initiator system comprising a Lanthanide or Transition metal oxidant; and
polymerizing the monomer in the reaction mixture to form a surface modification polymer on the surface of the silicon-containing polymer.
