A polymer is characterized by a repeat unit represented by Structural Formula (I): n n n n n n n n n n or a copolymer thereof. A crosslinked polymer characterized by a repeat unit represented by Structural Formula (II), (III), (IV) or (V): n n n n n n n n n n or a copolymer thereof, wherein at least one such repeat unit of a first polymer strand is crosslinked with at least one repeat unit of a second polymer strand by at least one bridging unit, the first and second polymer strands and the repeat unit being components of the crosslinked polymer. |
