Abstract
The courses of polymerization of 80 wt. % solutions of methyl methacrylate (NMA) In n-hexane (H), cyclohexane (CH), toluene (T), n-butyl acetate (BA), cyclohexanone (CON), dioxane (D), N-methyl pyrrolidone (MP). dimethylformamide (DMF), and Isobutyl alcohol (IBA) as the courses of polymerization of 80 wt. % solutionś of ethyl methacrylate (EMA) in dioxane (D), N-methyl pyrrolidone (MP), and Isobutyl alcohol (IBA) at 358 K in the presence of 5 mmol/L of 2,2'-azolsobutyronltrlle (AIBN) were measured in a differential scanning calorimeter DSC-2, Perkin Elmer. From the DSC curves the enthalpies of polymerization and the composite rate constants for the Initial steady state polymerization were calculated. It was found that the maximal reaction rate in the region of the gel effect and the composite rate constants are influenced by the solubility parameter of the solvent, i.e. the constants increase with the increasing value of the solubility parameter.
