Compositions comprising stereocomplexes of enantiomeric polymer chains having individual repeat units formed from the reaction of an epoxide and cyclic anhydride. The compositions can be made by mixing two types of enantiomeric polymer chains having opposite absolute stereochemistry. The compositions can be used in applications such as biomedical applications and drug delivery applications.

preference of substitution at the position ortho to the hydroxy group was observed for Ni-catalyzed cross-coupling reactions of dihalophenols with alkylGrignardreagents. Reactions of 2,4-dihalophenols, with various combinations of F, Cl, and Br, were shown to afford ortho-cross-coupled products selectively. In addition, high ortho preference was also observed in competitive cross-coupling reactions between
A medical adhesive composition comprising, based upon the total weight of the composition, from about 50 wt. % to about 99.9 wt. % of one or more α-cyanoacrylate monomers and from about 0.1 wt. % to about 5 wt. % of one or more non-steroidal anti-inflammatory drugs (NSAIDs). Suitable NSAIDs include ibuprofen and acetaminophen. The resulting compositions provide enhances fibroblast proliferation and reduced cytotoxicity compared to compositions that do not contain NSAID.
The present invention relates to active delivery system formulations, and methods of making and using the same. Said formulations, when applied to a substrate surface, form a protective coating on the surface and permit constituent active agents to act on the surface and in the surrounding medium.
