Modification of polymer surfaces
First Claim
1. A process for modifying polymer surfaces, comprising, exposing an organic modifier to actinic radiation while a polymer surface is in contact with said organic modifier, provided that the oxidation potential of the modifier minus the reduction potential of the polymer minus the excitation energy of the modifier is less than zero, further provided that said actinic radiation is of a wavelength that is absorbed by said modifier, further provided said polymer does not contain ethylenic unsaturation, and further provided that such modifier does not modify the polymer surface in the absence of actinic radiation:

Abstract
This invention concerns a process for modifying polymer surfaces by contacting the surface with a selected organic modifying agent while irradiating the surface with ultraviolet and/or visible light that can be absorbed by the modifier. Patterns of modified and unmodified surfaces can be produced. Polymers with modified surfaces are useful for absorbing biologically active molecules, composites, printing plates and electronics.
