- W4247467072 abstract "Polymeranalogous transformations due to the treatment of a compact polymer phase with liquid or gaseous agents lead—depending on the ratio of the diffusion penetration rate of the agent to the reaction rate—to more or less inhomogeneous products having a higher conversion on the surface than in the lower polymer layers. In some cases the above finding can be used for the preparation of laminated structures having certain advantages compared to similar systems obtained by coating the polymeric substrate with a film of a different polymer. The most important group has so far been represented by transformations of this type so chosen as to obtain thin layers exhibiting a specific chemical or biological activity on an inert substrate whose function is purely mechanical. Besides substitution transformations of hydrocarbon polymers by which e.g. ionizable groups are introduced, these reactions also involve chemical transformations of typical functional groups attached to a stable polymeric matrix. The foremost position in the latter category is held by acrylic and methacrylic polymers and copolymers in which it is possible to alter either the functions derived from the carboxylic group or functional groups attached by means of the ester or amide link. The introduction of strongly hydrophilic groups into the surface of hydrophobic linear polymers may lead to their release from the substrate. This may be prevented by introducing crosslinks via polyfunctional reaction components simultaneously with the hydrophilization transformatioa Such a precaution is not necessary for crosslinked polymers whose crosslinks resist chemical agents. Among these polymers a special role is played by macroporous gels, the large internal surface of which may be modified in many ways by chemical reactions of the functional groups." @default.
