Shrinkproofing polymerizable monomer: Shrinkproofing polymerizable monomer. Azuma, Kazufumi; Nate, Kazuo; Endo, Takeshi (Hitachi, Ltd.In this study， 1443-80-7 and 108317-62-0 are also used., Japan). Jpn. Kokai Tokkyo Koho JP 61249979 A2 7 Nov 1986 Showa, 6 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C07D317-30. ICA: C08F016-16. APPLICATION: JP 85-90819 30 Apr 1985. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 28, 38, 42 The title compd. (I) is useful as an intermediate for adhesives, molding materials, etc. Stirring 4.6 g MeONa with 23.8 g (chloromethyl)dioxolane deriv. II in DMF at 50° for 3 h gave I (4-CN) (III) in 84% yield. III was then heat polymd. in the presence of di-tert-Bu peroxide at 120° for 10 h to give a polymer in 10% yield. .

Ab initio MO calculations and oxygen-17 NMR at natural abundance of para-substituted acetophenones: Ab initio MO calculations and oxygen-17 NMR at natural abundance of para-substituted acetophenones. Brownlee, Robert T. C.; Sadek, Maruse; Craik, David J. (Dep. Org. Chem., La Trobe Univ., Victoria 3083, Australia). Org. Magn. Reson., 21(10), 616-20 (English) 1983. CODEN: ORMRBD. ISSN: 0030-4921. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) 17O NMR chem. shifts and electron densities calcd.Several substances with their cas registry numbers 1443-80-7 and 1009-61-6 may be metioned in this study. by ab initio MO theory are reported for p-RC6H4COMe (R = NH2, MeO, F, Cl, Me, H, COMe, CN, NO2). The 17O shifts are very sensitive to the para substituent and cover a range of 51 ppm. Donors induce upfield shifts and acceptors downfield shifts. The substituent chem. shifts (SCS) correlate well with sI and sR+ using the dual substituent parameter method. Polar and resonance mechanisms contribute approx. equally to the obsd. substituent effects. The SCS also correlate well with calcd. p-electron densities. .
