In situ functionalization of polymer materials in a polymer-forming and/or crosslinking (4) reactions based on addition or condensation reaction, comprises converting at least one polymer former comprising e.g. lactams with at least one modifier consisting of e.g. 1-20C alcohols, where polymer formers and modifiers are present in phases which are not miscible with each other so that essentially terminal covalent bonding of at least one modifier to at least one polymer former is effected at interface of phases, as result of which modifier accumulates essentially on surface of polymer material.; In situ functionalization of polymer materials in a polymer-forming reaction and/or crosslinking (4) reaction based on an addition reaction or condensation reaction, comprises converting at least one polymer former comprising lactams, diamines, dicarboxylic acids, dicarboxylic acid chlorides, vinyl alcohols, diols, diesters, diisocyanates, diary lcarbonates, imides, epoxides, diepoxides, dicarboxylic acid anhydrides and their oligomers or polymers constructed from those monomers, with at least one modifier consisting of 1-20C alcohols, 1-20C fluorinated alcohols, 1-20C acids, 1-20C fluorinated acids, 1-20C acid anhydrides, 1-20C fluorinated acid anhydrides, 1-20C primary amines, 1-20C fluorinated primary amines, 1-20C secondary amines, 1-20C fluorinated secondary amines, 1-20C tertiary amines, 1-20C fluorinated tertiary amines, 1-20C isocyanates, 1-20C fluorinated isocyanates,; 1-20C thioisocyanates, 1-20C fluorinated thioisocyanates, 1-20C carbonyls, 1-20C fluorinated carbonyls, substituted arylene, fluorinated substituted arylene, unsubstituted arylene, fluorinated unsubstituted arylene, epoxides, multifunctional compounds, glycols, polyols, saccharides, oligosaccharides, polysaccharides, diamines, polyamines and/or mixed functional compounds, where the polymer formers and modifiers are present in phases which are not miscible with each other so that essentially terminal covalent bonding of at least one modifier to at least one polymer former is effected at the interface of the phases, as a result of which at least one modifier accumulates essentially on the surface of the polymer material. Independent claims are also included for: (1) a polymer material with a functionalized surface, produced by the above method; and (2) functionalizing a substrate surface comprising utilizing the polymer material in a functionalizing step.
