    摘要: An apparatus and method for continuous, passive detection and measurement of tensile and compressional strain in a structure utilizing a shielded optic fiber, the optic fiber having one or more Bragg gratings thereon, the gratings and shield being disposed in a curved path on the structure and a baseline response for the grating is made using an optical source and detector. Changes in tensile or compressional forces on the structure will result in changes in the curve of the grating, resulting in a frequency shift for the returned light.

    摘要: This invention is an improvement upon the current process for the production of block copolymers, especially hydrogenated block copolymers, of conjugated dienes and/or vinyl aromatic hydrocarbons which comprises anionically polymerizing the monomers in an inert hydrocarbon solvent in the presence of an alkali metal initiator whereby a polymer cement is produced and then contacting the cement with hydrogen under hydrogenation conditions in the presence of a hydrogenation catalyst. This invention and the improvement to the foregoing process comprises reducing the viscosity of the polymer cement by adding to it, preferably prior to hydrogenation (if the polymer is to be hydrogenated), from 2 to 50 % wt of a polar compound. The polar compound must be a poorer solvent for the block copolymer than is the inert hydrocarbon solvent. Preferred polar compounds include diethyl ether, tetrahydrofuran, diethoxyethane, monoglyme, diglyme, diethoxypropane, dioxane ortho-dimethoxybenzene, and the like.
