Mixed organic and inorganic polymers

摘要

A polymer is characterized by a repeat unit represented by Structural Formula (I):;
or a copolymer thereof. A crosslinked polymer characterized by a repeat unit represented by Structural Formula (II), (III), (IV) or (V):
;
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.

1. A crosslinked polymer characterized by a repeat unit represented by the following structural formula: or a copolymer thereof, wherein:
the polymer is crosslinked with at least one crosslinking agent, wherein the crosslinking agent is hexamethylenetetramine;at least one 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;each Q is an optionally substituted alkylene group that is optionally interrupted with one or more heteroatoms selected from the group consisting of oxygen and sulfur;Z is —N(R2)—C(O)-T1-G-E-G-T2-C(O)—N(R2)— or —X1—B1—X2—;each G independently is a covalent bond, an optionally substituted aryl ring group, an optionally substituted heteroaryl ring group, an optionally substituted non-aromatic hydrocarbyl ring group, or an optionally substituted non-aromatic heterocyclic ring group;E is a covalent bond, —O—, —S—, R′, —O—R′—O—, —S—R′—S—, —C(O)—, —N(R)—, —N(R)C(O)— or —N(R)C(S)—;
each of T1 and T2 independently is a covalent bond or an alkylene group, or, taken together with N(R2)—C(O)—, forms a 5-14 membered non-aromatic heterocyclic group, provided that when both of T1 and T2 are covalent bond, at least one G is other than a covalent bond;B1 is an optionally substituted alkylene group that is optionally interrupted with one or more heteroatoms selected from the group consisting of oxygen and sulfur, or an optionally substituted aryl group;each of X1 and X2 independently is O, S or NR; each R independently is —H, an optionally substituted alkyl group or an optionally substituted aryl group;
each R′ independently is an optionally substituted hydrocarbylene group;each R1 independently is —H, an optionally substituted alkyl group, an optionally substituted alkoxy group, an optionally substituted aryloxy group, or an optionally substituted aryl group;each R2 independently is —H, an optionally substituted alkyl group or an optionally substituted alkylcarbonyl group, or each R2 independently, taken together with the nitrogen atom and the carbonyl group of —C(O)—N(R2)—, and together with T1 or T2, forms a 5-14 membered non-aromatic heterocyclic group optionally fused with G when G is other than a covalent bond; andeach x is an integer of 1-50.
