Surface modification of polymeric objects |
摘要 |
A class of polymerizable surfactants are described by the formula DC(AxBy) wherein A is a monomer unit derived from at least one ethylenically unsaturated hydrophilic monomer, B is a monomer unit derived from 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. The polymerizable surfactants are useful for modifying the surfaces of polymeric objects, especially contact lenses.
