✦ Synopsis

Several monomers have been polymerized using %,l'-azobis(1-phenyl I-13C] ethane as initiator~ the initiator fragments incorporated in the polymers have been examined by 13C-N~. The chemical shift for the enriched site in the end-group depends upon the nature of the attached monomeric unit. It is concluded that acanaphthylene is suitable as a reference monomer in comparisons of the reactivities of monomers towards the 1-phenylethyl radical (regarded as a model for the polystyrene radical) by consideration of end-groups in copolymers.

## Abstract The reliable estimation of monomer reactivity ratios is a key problem in the development of process models, and, thus, is an important issue in both process design and control. Copolymers of isobutyl methacrylate (i‐BMA), and lauryl methacrylate (LMA) were prepared by free radical bulk
