Abstract: A composition includes a polyester urethane. The polyester urethane includes a crosslinker based on diisocyanate and an alternating copolymer resin of polyol and polyacid. The resin has a degree of branching, weight average molecular weight, polydispersity index, and viscosity prior to the crosslinking. The polyester urethane has a microstructure of hard segments and soft segments based on a selected combination of polyol, polyacid, degree of branching, the weight average molecular weight, the polydispersity index, the viscosity, the diisocyanate, the first stoichiometric ratio, and the second stoichiometric ratio. The microstructure provides a predetermined property to the composition selected from a degradation rate in an aqueous environment, release rate of a drug loaded in the polyester urethane in the aqueous environment, solubility of the drug, and combinations thereof.

Abstract: In some embodiments, a polymer film includes a base composition of poly(ethylene-vinyl acetate) and a surface composition comprising hydroxy groups. In some embodiments, a polymer film includes a base layer of a first composition of poly(ethylene-vinyl acetate), a surface layer at a surface of the base layer, and a coating layer of a second composition of a copolymer of glycerol and sebacic acid. The surface layer includes surface hydroxy groups converted from acetate groups of the poly(ethylene-vinyl acetate). The second composition is attached to the surface layer by ester bonds between carboxyl groups of the copolymer and the hydroxy groups. A single-use bioreactor bag includes a polymer film including a base composition of poly(ethylene-vinyl acetate) and a surface composition comprising hydroxy groups. A method of modifying a poly(ethylene-vinyl acetate) film includes converting acetate groups at a first surface of the poly(ethylene-vinyl acetate) film to hydroxy groups.

Abstract: A water-mediated process prepares a polymeric (meth)acrylation composition. In some embodiments, the process includes providing a stabilized aqueous solution including a (meth)acrylation component and a polyol monomer in a vessel under an inert atmosphere and adding a diacid monomer to the vessel under the inert atmosphere. In some embodiments, the process includes providing a stabilized aqueous solution including a (meth)acrylation component and a copolymer of a polyol monomer and a diacid monomer in a vessel under an inert atmosphere. The process further includes heating and removing water from the vessel under the inert atmosphere to produce the polymeric (meth)acrylation composition. The polymeric (meth)acrylation composition includes a (meth)acrylation polyester copolymer of the diacid monomer and the polyol monomer with the (meth)acrylation component conjugated to the (meth)acrylation polyester copolymer.
