Abstract
The present invention is directed to a compound of formula I, wherein R1 comprises hydrogen, an alkyl group, or an aryl group; R2 comprises hydrogen or a methyl group; R3 comprises a divalent organic group; R4 comprises a divalent organic group; and X comprises oxygen, NH, or N(R5), wherein R5 comprises a monovalent organic group. The present invention is also directed towards polymers comprising a pendant carbamate-functional moiety comprising the structure: wherein R1 comprises hydrogen, an alkyl group, or an aryl group; R2 comprises hydrogen or a methyl group; R3 comprises a divalent organic group; R4 comprises a divalent organic group; and X comprises oxygen, NH, or N(R5) wherein R5 comprises a monovalent organic group. The present invention is also directed to methods of preparing such compounds and polymers, compositions comprising such polymers, and coatings produced from such compositions.
