Abstract
The surface of a polymer material is modified by adding to the material a block copolymer. The block copolymer has a hydrophilic polymer portion and a polymer portion which is compatible with the polymer material to be modified. The block copolymer can be easily synthesized in the presence of a polymeric peroxide and can easily and permanently modify the surface of the polymer material.
