A functionalized polyurethane polymer is provided, the polymer defined by the formula where each R' is independently derived from a diisocyanate, where each R&#x2033; represents the soft segment of the polymer, where n is the number of repeat units within the soft segment of the polymer, where m is the number of repeating mer units in the polymer, where each E is a pendant-functionalized amide unit chain extender, wherein the nitrogen atom of the amide group is part of the polymer backbone. A method for preparing the polymer is also provided.

Polymers including &#x3b1;-hydroxymethylacrylate units and methods of preparing polymers from &#x3b1;-hydroxymethylacrylates are provided. Advantageously, &#x3b1;-hydroxymethylacrylates may be used in an emulsion polymerization and function as a polymerizable surfactant. The ability of the &#x3b1;-hydroxymethylacrylates to be used as a polymerizable surfactant allows for emulsion polymerization systems to be prepared without other surfactants.

A method of preparing a polymer is provided comprising preparing a Baylis-Hillman adduct by reacting an activated alkene with a carbon electrophile; and polymerizing the Baylis-Hillman adduct. The Baylis-Hillman reaction provides an efficient platform for the synthesis of densely functionalized monomers, from which polymers with multiple functional groups can be readily synthesized. It has been discovered that that Baylis-Hillman adducts are versatile monomers for both controlled radical and step-growth polymerizations.
