Abstract
The present invention relates to the preparation of polymers bearing reactive functional groups. More particularly, this invention relates to the preparation of polymers containing functional acetoacetate groups and then following the polymerization reacting the acetoacetate group with a functional amine to form an enamine. Polymers of the present invention have many uses including coatings, sealants, adhesives and saturant applications, and are most useful as solutions or dispersions in water or water-cosolvent mixtures.
