NMR characterization of functional groups: 9 - isomer ratios of available chloromethylstyrene mixtures

NMR characterization of functional groups: 9 - isomer ratios of available chloromethylstyrene mixtures. Manatt, Stanley L.; Khune, G. D.; Khatri, N. A. (Jet Propul. Lab., California Inst. Technol., Pasadena, CA 91109, USA). Magn. Reson. Chem., 23(3), 207-12 (English) 1985. CODEN: MRCHEG. ISSN: 0749-1581. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 25, 80 From the assignments of the 1H and 13C 11.7 T NMR spectra for mixts. of m- and p-chloromethylstyrene from 2 common com. sources, the proportion of meta and para derivs. were 72 and 28 and 68 and 32%, resp. The influence of the difference between these percentages and the often assumed 60 and 40% for the meta and para derivs., resp., on the desired properties of copolymers made from such mixts. was discussed. An alternative quant. procedure for detg. the chloromethyl group isomer ratios was also described which employed Ag trifluoroacetate [2966-50-9] displacement of chloride and 19F NMR examn. of the resulting ester mixt. with a 2.3 T spectrometer.

DOCUMENT TYPE: Patent CA Section: 76 (Electric Phenomena) Section cross-reference(s): 73, 74 A method of creating microstructures by contact transfer process includes the step of positioning a material covered ribbon in proximity with the surface of the substrate, directing a laser beam onto the material covered ribbon, so that the laser beam releases a portion of the material layer and transfers the released material onto the surface of the substrate. The material covered ribbon includes a transparent support and a material layer of the thickness in the range of 2-15 mm of highly homogeneous and uniformly distributed material, which includes a powder of very small particles the dimensions of which do not exceed 10 mm bound by a binder which provides a needed degree of viscosity to the material, which, being released from the material layer, is transferred to the surface of the substrate as a single piece. In order to create a microstructure, several repetitions of releasing the material and transferring the released material to the substrate is needed. Very fine features with no edge irregularities are created by this method. When the material used is, e.g., silver, the material layer may be formed with a precursor such as silver trifluoroacetate which yields silver when decompd. .
