- W2326693419 abstract "The polymerization of methyl methacrylate (MMA) was investigated by use of cholesterol (Chol) as an initiating radical source. Chol showed initiating ability of polymeri zation in the presence of a small amount of Fe(III) salts, such as FeCl3 or Fe2(SO4)3 (the optimum ratio of Chol to Fe(III) salts existed; Fig.1), although the polymerization was not induced by Chol alone. The polymerization was inhibited by the addition of p-benzoquinone. The overall activation energies for the polymerization were estimated to be 42.9 kJ⋅mol-1 (for FeCl3 system) and 49.7 kJkJ⋅mol-1 (for Fe2(SO4)3 system), respectively. The kinetic study was made keeping the ratio of Chol to FeCl3 constant ([Chol]/[FeCl3] =50; Table 1 and Fig.5), and the rate of polymerization (Rp) was given by the following equation:Rp=k[MMA] [Chold-FeCl3]0.5Radical initiating polymerization was as sumed to be produced through the redox reaction between the hydrogen at 17-position of Chol and Fe(III)." @default.
