✦ Synopsis

The kinetics of free radical polymerizations of methyl and butyl acrylate were studied in benzene at 50:. The initiation rate constant determined by the inhibition method was found to be constant over the whole monomer solvent composition range in both systems. The polymerization rate was investigated as a function of initiator and monomer concentrations. In accordance with theory, an initiator order of 0.5 was obtained for both systems: monomer orders > I were found. This solvent effect could not be explained either in terms of the diffusion theory or by the thcory of EDA complexes; complete agreement was found between experimental results and the theory of hot radicals.

An experimental investigation of the kinetics of the bulk free radical polymerization of butyl acrylate initiated with 2,2'-azobisisobutyronitrile ( AIBN ) was conducted at 50" and 60°C using two initiator concentrations. Conversion levels were measured by gravimetry and were independently confirmed

The kinetics of methyl acrylate polymerization initiated by azobisisobutyronitrile were investigated in dimethylformamide at 40-60. The polymerization was 1/2 order with respect to initiator; the rate of initiation was independent of the initial concentration of monomer. The rate and the overall rat

Solution copolymerizations of butyl acrylate/methyl methacrylate in toluene were performed over an expanded temperature range (60 -140°C) compared to more typical ranges that do not exceed 80°C. From a large amount of data collected independently at two laboratories, reactivity ratios were estimated

## Abstract Branch lengths resulting from both backbiting and intermolecular chain transfer to polymer are examined for the solution polymerization of butyl acrylate, using a rate‐equation model and ordinary differential equations. Backbiting is allowed to generate branches of varying length, accor
