摘要： The present invention provides a modified conjugated diene polymer that has excellent hydrophilicity and is useful for modification of polar polymers. The present invention also provides a modified conjugated diene polymer and a polymer modifier that, when used for modification of a polar polymer, can enhance characteristics, for example, flexibility, of the composition including the polymer and also offer excellent processability and shaping properties. The present invention further provides a polymer composition including such a conjugated diene polymer. A polymer modifier (A) includes a modified conjugated diene polymer (A1) having a hydrophilic group having a polyethylene glycol structure.

摘要： Water-absorbent resin particles having a degree of gel association of 15 or more, the degree of gel association being measured by the following procedures (1) to (4) are disclosed. (1) 1.0 g of water-absorbent resin particles is disposed in a graduated cylinder having a cylindrical part and a pedestal part, and then 50 ml of pure water is injected to form a swollen gel, (2) a tubular body having a circular opening is prepared, where the tubular body is fixed in a state where both end portions are open in a vertical direction, and a flat portion is provided at an upper end portion, and ten minutes after completion of injection of the pure water, the cylindrical part of the graduated cylinder is inserted into the tubular body so that an opening part of the graduated cylinder faces vertically downward, and thereby the pedestal part of the graduated cylinder is supported by the flat portion of the tubular body, (3) in a state where the tubular body is fixed, the graduated cylinder is freely dropped to cause the pedestal part of the graduated cylinder to collide with the flat portion of the tubular body, and (4) the operation of (3) is performed at intervals of 10 seconds, and the number of times of causing the graduated cylinder to collide with the tubular body until 1 g or more of the swollen gel is dropped is measured as the degree of gel association.

摘要： An object is to provide a novel modified polypropylene resin which makes it possible to provide, by an extrusion expansion method, expanded polypropylene-based resin particles having an expansion ratio which falls within a wide range and having a low open cell ratio. The object is attained by providing a method of producing a modified polypropylene resin, the method including a melting and kneading step of melting and kneading a particular random polypropylene resin, a conjugated diene compound, and a particular radical polymerization initiator to obtain a modified polypropylene resin.

摘要： The decarboxylation of N-oxyphthalimide-based polyolefin-precursor polymers, copolymers and block copolymers is suitable for radical based post-polymerization modifications. The removal of the N-oxyphthalimide side group on the one hand gives the opportunity to develop a new and innovative method for the synthesis of well-defined polyolefin-like structures and on the other hand allows for the introduction of new functional groups to a polymeric system, realized by thermally- or photo-induced decarboxylation reactions based on transition metal redox catalysis.
