## Abstract The terminal and penultimate model reactivity ratios in the free‐radical copolymerization of styrene and methyl methacrylate in bulk at 40°C were calculated by means of the simplex and scanning methods. Calculations showed that for the terminal model __r__~1~ and __r__~2~ vary in compar

## Abstract Statistical copolymers of isobutyl methacrylate and lauryl methacrylate were prepared by free radical bulk copolymerization at 70 °C using 2,2′‐azobisisobutyronitrile as initiator. The synthesis of these copolymers was investigated over a wide composition range at low conversion levels.
## Abstract A newly developed method for the determination of the radical reactivity ratios is presented. Two main equations are used and the parameters can be calculated from the ordinate and the slope of the linearization plots. Both equations yield identical values when applied to synthetic data
