Abstract

See full text

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. In some embodiments, the polymeric (meth)acrylation composition is free of mineral acid and free of cytotoxic solvents, catalysts, and scavengers.
