<p>A polymer member which has a multilayer structure comprising a polymer layer and a monomer-absorbing layer capable of absorbing at least one monomer ingredient constituting the polymer, characterized in that the polymer layer is an incompatible-substance-unevenly-containing polymer layer in which a substance incompatible with the polymer is distributed either at the interface on the side opposite to the monomer-absorbing layer or in an area near that interface in a higher concentration than in other parts. The polymer member preferably has a cover film superposed on the polymer layer on the side opposite to the monomer-absorbing layer. The area near the interface on the side opposite to the monomer-absorbing layer preferably is a region ranging from the interface on the side opposite to the monomer-absorbing layer in the thickness direction to up to 50% of the overall thickness.</p> |
