55913s Optimal control of polymerization reactors. Hicks, James; Mohan, Amar; Ray, Willis Harmon (Dep. Chem. Eng., Univ. Waterloo, Waterloo, Ont.). Can. J. Chem. Eng. 1969, 47(6), 590-7 (Eng). The optimal control policy for continuous stirred tank polymn. reactors and the optimal control program for batch polymn. reactors are discussed. The first problem concerns detg. the temp. and initiator control policy which brings the reactor to the desired steady state while minimizing some objective functional (e.g. start-up time, cost of control action, etc.). The second problem is concerned with finding the temp. and initiator program so that the product from the batch reactor has the best possible mol. wt. distribution. Both free-radical polymn. and linear condensation polymn. examples are considered with mol. wt. distribution moments being used to characterize the polymer. Kinetic parameters typical of styrene are used for the free radical case, and realistic parameters are chosen for the condensation examples. Some of the potential gains possible through supervisory computer control of polymn. reactors are demonstrated. RCHC

Van’t Hoff law of OSMOTIC PRESSURE variation with concn. was studied for dil. solns. of sucrose [57-50-1], dextran, and poly(vinylpyrrolidone) (I) [9003-39-8]. Due to solvent constraints, the solutes were changed from their preferential, unperturbed state causing a pressure shock which modified the mol. CONFIGURATION.

105898x Preparation and synthetic utility of ω-vinylperfluoro-alkanecarboxylates. Kim, Yung K.; Pierce, Ogden R. (Fluorine Res. Lab., Dow Corning Corp., Midland, Mich.). J. Org. Chem. 1969, 34(3), 602-5 (Eng). The addn. of ethylene to ethyl ω-bromoperfluoroalkanecarboxylates under free-radical conditions gave the desired 1: 1 adduct, BrCH2CH2 (CF2CF2)nCOO2Et, in good yield along with the 1 :2 adduct, Br(CH2CH2)2(CF2CF2),CO2Et, and a little of the higher telomers. Treatment of the I : 1 adduct with NaOEt resulted in the formation of Et ω-(vinyl)perfluoroalkanecarboxylates in high yield. Et 3-(vinyl)perfluoro-propionate was converted into 3-(vinyl)perfluoropropionitrile (I) via the corresponding amide. The synthetic approach leading to a fluorosilicone-triazine polymer, -[-SiMe(CH3)(CF3CH2CH2)CH2CH2CF2CF2 (CF3C3N3)-CF2CF2CH2CH2 (CF3CH2CH2)MeSiO-]-, (where CF3C3N3 is 6-trifluoromethyltriazine-2,4-diol), by utilization of I is described.
