    摘要： A resin composition for forming an etching mask pattern, with which a phase-separated structure having a period (L0) of less than 20 nm and having excellent vertical orientation even when subjected to high-temperature annealing can be obtained; and a method for manufacturing an etching mask pattern. The method includes applying the resin composition onto a support to form a block copolymer layer having a film thickness of 25 nm or more and phase-separating the block copolymer layer. The resin composition contains a block copolymer having a first block and a second block, the first block includes a structure of General Formula (b1), and the second block consists of a block 2M of a structure of General Formula (b2m) and a block 2G of a structure of General Formula (b2g), and y/(y+z) is 0.01 or more and 0.11 or less; R1 is an alkyl group, R2 is an alkyl group; and R3 is an alkylene group

    摘要： An aqueous composition includes water and a cationic polymeric resin having at least one reactive aldehyde group and formed from the reaction of glyoxal and a polymer. The polymer comprises at least one acrylamide repeating unit and at least one cationic repeating unit wherein a number of reactive aldehyde equivalents divided by a number of equivalents of residual glyoxal based on the total weight of the polymer is greater than about 1.2, wherein prior to reaction the polymer has greater than about 50 mole % acrylamide repeat units and from about 2 to about 30 mole % cationic repeating units, wherein greater than about 5 mole % of the acrylamide repeating units are converted to reactive aldehyde groups in the cationic polymer resin; and wherein the composition exhibits a viscosity gain of less than about 200%.

    摘要： The present disclosure relates to a catalyst composition for polymerizing propylene and a method for producing polypropylene. The catalyst composition for polymerizing the propylene includes a modifying agent. The modifying agent is an ester compound having hydrophilic groups and hydrophobic groups. In the method for producing the polypropylene, a reverse microcellular structure is formed by the modifying agent during a propylene polymerization, in which the hydrophilic groups are inside the reverse microcellular structure, and the hydrophobic groups are outside the reverse microcellular structure, such that polar substances in a raw material are retained inside the reverse microcellular structure. Thus, poisoning of the catalyst is reduced. Besides, the modifying agent can maintain a valence state of titanium in an active site of the catalyst at positive trivalent, such that the propylene polymerization between the titanium and the monomer is facilitated, thereby enhancing an activity of the catalyst.
