Abstract: A method for controlling a particle diameter and a particle diameter distribution of emulsion particles during manufacturing of an emulsion dispersion is provided. The method includes causing two or more types of liquids substantially immiscible with each other to continuously and sequentially pass through net bodies. The net bodies are disposed in a cylindrical flow passage at intervals of 5 to 200 mm, and the number of the net bodies is more than 50 and 200 or less. Each of the net bodies is equivalent to a gauze having a mesh number of 35 mesh to 4000 mesh in accordance with an ASTM standard and has a surface that intersects the direction of the flow passage. An emulsification apparatus used for the method includes a feed pump for feeding two or more types of liquids substantially immiscible with each other; and a cylindrical flow passage to which the two or more types of liquids fed by the feed pump are delivered.

Abstract: A method for selectively producing a monoaryl norbornene derivative represented by a formula (5) involves having a norbornadiene derivative represented by a formula (3) and a bromine compound represented by a formula (4) react with each other in the presence of a reducing agent, palladium and at least one selected from phosphorus compounds represented by the formulas (1) and (2), whereby the norbornene derivative represented by formula (5) having a monoaryl substituent is an exo configuration.

Abstract: During the manufacture of a master batch for a polyolefin resin film, organic polymer fine particles which contain a polyfunctional monomer (cross-linking agent) having at least one kind of two or more functional groups in a monomer unit constituting a polymer and is mixed with a polyolefin resin using an extruder are blended as an anti-blocking agent, thereby preventing the generation of die build-up around the outlet of the extruder.

Abstract: A retardation film, formed by stretching a film including a norbornene-based, ring-opening polymer containing a structural unit (A) represented by a formula (1), has high transparency, excellent wavelength dispersion characteristics in a single layer, is capable of providing specific retardation to broadband light, is extremely adhesive to other materials, is capable of attaining optical characteristics that are unique among negative birefringence characteristics, and is capable of providing a reverse dispersion of birefringence wavelength dispersion characteristics. The present invention also provides a liquid crystal display device using the foregoing film.

Abstract: An anti-blocking agent master batch is provided, obtained by compounding 100 parts by mass of a polyolefin-based resin with 1 to 40 parts by mass of polymer fine particles, the polymer fine particles obtained by: causing two or more fluids including a liquid medium, a monomer or monomers, and a polymerization initiator to continuously and successively pass through a plurality of net bodies which are disposed at given intervals in a cylindrical passage and each have a surface crossing a direction of the passage to obtain an emulsion including liquid droplets containing the monomer or monomers and the polymerization initiator, the liquid droplets being dispersed in the liquid medium; and heating this emulsion to polymerize the monomer or monomers. Also provided is a manufacturing method thereof.
