Amine-functional polymers and methods for producing such polymers

Abstract

A process for producing a β-amino ester functionalized oligomer or polymer, said process comprising the steps of: providing a polyol represented by the formula A-(OH)q wherein q≥2 and A denotes an oligomeric or polymeric backbone, and converting said polyol into its corresponding acetoacetate functionalized compound by transacetoacetylation with an acetoacetate reagent; and, subjecting said acetoacetate functionalized compound to either indirect amination or direct reductive amination. Said indirect amination may be characterized by comprising the steps of: converting the acetoacetate functionalized compound into its corresponding enamine by reaction with at least one amine bearing at least a primary or secondary amine group; and, reducing the enamine product of the previous step to form the corresponding β-amino ester functionalized compound.
