Abstract:
1. A polymeric film comprising a reactive and multifunctional copolymer comprising a first substituted p-xylylene unit having a first reactive functional group, wherein the first substituted p-xylylene unit is introduced at a first position with respect to a substrate on which the copolymer is formed so that distribution of the first substituted p-xylylene unit in the copolymer forms a first compositional gradient in a first direction in the film and a second substituted p-xylylene unit comprising a second reactive functional group distinct from said first reactive functional group, wherein the second substituted p-xylylene unit is introduced at a second position with respect to the substrate so that said second substituted p-xylylene unit forms a second compositional gradient in a second direction in the film, wherein at least one of the first and second compositional gradients corresponds to an x-dimension or a y-dimension of the film and the first position and second position are distinct from one another.
