Abstract: Disclosed are methods for the heterogeneous catalytic transesterification of compounds having one or more ester groups and groups reactive under transesterification conditions, such as 1,1-disubstituted alkene compounds, with alcohols or esters and novel compositions prepared therefrom. Further disclosed are novel compounds and compositions prepared as a result of the methods.

Abstract: The disclosure relates to compositions containing 1,1-di-substituted alkene compounds capable of preparing polymers having glass transition temperatures above room temperature. The present teaching also relates to polymers prepared 1,1-di-substituted alkene compounds which exhibit glass transition temperatures of 60° C. The disclosure also relate to methods for enhancing the glass transition temperatures of polymers prepared from 1,1-di-substituted alkene compounds.

Abstract: Disclosed are graft copolymers, compositions including graft copolymers, intermediate materials, and related methods, where the graft copolymer includes a first polymer component including a 1,1-disubstituted-1-alkene compound (preferably a methylene malonate compound) and is grafted to a second component. The resulting graft copolymer may be hydrophilic or water soluble. The second component preferably is a hydrophilic component.
