## Abstract A new technique to determine the reactivity ratios for monomers is described. It is based on vaporβphase chromatography and can be used for any volatile monomer. A new simplified equation was deduced which permits the direct use of the retention times to obtain the pair __r__~1~__r__~2~
Methacrylonitrile/butyl acrylate (M/B) copolymers were prepared by bulk polymerization using benzoyl peroxide as an initiator. The Distortionless Enhancement by Polarization Transfer spectra were used to differentiate between the carbon resonance signals of methyl, methine, methylene and oxymethylen
