Abstract
Polymeric materials are disclosed in which a synthetic essentially hydrophobic base polymer has at least in its surface region a crosslinked polar comonomer graft in the surface region at least of which there are metal atoms or ions which are chemically bound and which cannot be removed by solution processes. There are also disclosed three processes by which such materials may be produced. The deposition of a complex metal compound, the contacting of the graft with a metal compound both followed by heating, and graft copolymerization with a metal containing comonomer. There is also disclosed a method of ensuring a good bond between a polymeric material and a coating which includes a preliminary surface graft with a polar comonomer.
