A process of forming a lactide copolymer includes forming a dimethylidene lactide molecule from an L-lactide molecule. The process also includes forming a functionalized lactide monomer from the dimethylidene lactide molecule. The process includes forming a mixture that includes the functionalized lactide monomer and a bisphenol A (BPA) monomer or a BPA-derived monomer. The process further includes polymerizing the mixture to form a lactide copolymer.

A process for preparing a low-molecular weight fluoropolyether containing an acid fluoride by decomposing a triflate or trifluoroacetate of a fluoropolyether having a hydroxyl group in the presence of a Lewis acid.

The present invention provides adhesive hydrogels that negatively swell at physiological temperature. By combining mussel-mimetic chemistry and the thermosensitive nature of poly(ethylene oxide)-poly(propylene oxide) copolymers, novel materials were designed that are suitable as medical sealants and adhesives.
