Patent ID: 8790701

Claim:
A biodegradable, biocompatible crosslinked polymeric matrix comprising crosslinked poly-α(1→4)glucopyranose polymers and a linker between the poly-α(1→4)glucopyranose polymers having Formula IIIa, Formula IIIb, Formula IVa, or Formula IVb: where, in Formula IIIa or IVa, Q 1 and Q 2 represent monomeric units of the α(1→4) glucopyranose polymers; R 3 is a cyclic, linear, or branched carbon-containing group, R 5 is O, or a cyclic, linear, or branched carbon-containing groups that contain one or more heteroatoms selected from the group of oxygen and nitrogen; or in Formula IIIb or IVb, Q 3 and Q 4 represent monomeric units of α(1-4) glucopyranose polymers, and R 6 is a covalent bond, or a cyclic, linear, or branched carbon-containing groups that contain one or more heteroatoms selected from the group of oxygen and nitrogen.
