    摘要: The present invention pertains to a method for forming polyacrylic acid granules and granules formed therefrom wherein the granules are flowable, have an increased bulk density relative to the as polymerized polyacrylic acids, and a low amount of dust which is generally characterized herein as particles which pass through a 325 mesh screen. The granules formed by the method of the present invention can be used to prepare controlled release tablets, especially controlled release pharmaceutical tablets. The controlled release properties of the tablets formed from granules prepared according to the present invention are unexpectedly better than tablets prepared from granules formed by other known granulation methods.

    摘要: The invention relates to a method for the production of a template-textured material by synthesis of a template-textured polymer (TTP) by performing crosslinking polymerization of functional monomers on a support in the presence of a template, which method is characterized in that a support having a thin polymer layer on the surface thereof is added with a reaction mixture consisting of polymerization initiator, template, functional monomer, crosslinker, solvent and/or buffer and, following sorption of the reaction mixture in the thin polymer layer, the polymerization is initiated and continued until the absorption capacity of the thin polymer layer for the template-textured polymer (TTP) is reached, and the template is optionally removed in a final step, the support used being selected in such a way that it cannot absorb the reaction solution. The materials of the invention are remarkable for their high binding specificity and selectivity for the template.

    摘要: This invention relates to an acrylonitrile-based precursor fiber for the formation of a carbon fiber which is obtained by spinning an acrylonitrile-based copolymer (which contains not less than 90% by weight of acrylonitrile units as monomeric components, contains 5.0×10−5 to 2.0×10−4 equivalent/g of carboxylic acid groups and not less than 0.5×10−5 equivalent/g of sulfate groups and/or sulfonic groups, and has protons and/or ammonium ions as counter ions to the carboxylic acid groups, sulfate groups and sulfonic groups) and treating the resulting coagulated filament, wherein the amount of iodine adsorbable to the acrylonitrile-based precursor fiber is not greater than 0.8% by weight based on the weight of the fiber. By using this precursor fiber, a carbon fiber having a high strength and a high elastic modulus can be easily formed.
