Castor-Acrylated Monomer H-1- and C-13-Nuclear Magnetic Resonance Spectral Assignments
Polymers and High Performance Materials
Castor-acrylated monomer (CAM) NMR spectral assignments were made utilizing one- and two-dimensional NMR techniques. The unique structure of CAM resulted in several novel chemical environments which were observed in the NMR spectra. Previously published vegetable oil and fatty acid ester NMR peak assignments were insufficient for complete identification of NMR peaks. Definitive peak assignments, particularly in the alkyl and alkene regions, are required for evaluation of CAM as a specialty comonomer in the synthesis of latex polymers for use as waterborne-coating binders. The NMR peak assignments for CAM will allow the subsequent evaluation of the copolymerizability of CAM as well as the determination as to whether unsaturation is preserved during latex polymer synthesis. H-1- and C-13-NMR spectra of CAM are provided with supporting evidence for the peak assignments and discussion of their relevance. (C) 2001 John Wiley & Sons, Inc.
