Abstract
A process for surface modifying a variety of polymeric support surfaces is disclosed in which a predetermined modifying polymer is irreversibly absorbed onto essentially all the surfaces of the support polymer accessible to the modifying polymer. The modifying polymer is selected to impart the desired surface characteristics to the modified polymeric surface.
Claims36
A process for surface modifying a predetermined polymeric support material which comprises irreversibly adsorbing a modifying polymer onto substantially the entire surface of said support material accessible to said modifying polymer, said modifying polymer having a molecular weight of at least 10,000 and containing an effective number of binding groups which partition onto or into the support material and adhere the modifying polymer to the support material, and subsequently removing excess non-adsorbed modifying polymer by washing the modified polymeric support material.
