    Abstract: PURPOSE:To obtain a composition having remarkably improved moldability without lowering the mechanical and thermal properties by compounding a polyarylene polyether sulfone, a thermotropic liquid crystal polyether and a fibrous inorganic filler. CONSTITUTION:The objective composition can be produced by compounding (A) 60-9.95 pts.wt. of a polyarylene polyether sulfone. (B) 40-0.05 pts.wt. of a thermotropic liquid crystal polyester and (C) 5-45 pts.wt. (based on 100 pts.wt. of A+B) of a fibrous inorganic filler. The component A is a polymer having the recurring units of formulas I and II and is polyether sulfone or polysulfone. The component B is a polymer containing >=20mol% of the recurring unit of formula III and the component C is selected from glass fiber, carbon fiber and potassium titanate fiber.

    Abstract: PURPOSE:To obtain an aromatic polyether having excellent heat stability and a wide range of molding temperature and not suffering thickening and coloration even in recycle molding by using a specified terminal group as the terminal structure of an aromatic polyether. CONSTITUTION:The title aromatic polyether is one represented by formula I, wherein the terminal group Z is represented by formula II. In the formulas, E is a dihydric phenol residue, E' is a dihalogenobenzenoid compound residue having a structure of formula III, X is SO2 or CO; n >=10; Y is H, a halogen atom, a group of formula IV or V or the like. An aromatic polyether is generally synthesized by, for example, preparing a dialkali metal diphenolate from a dihydric phenol and an aqueous solution of an alkali metal hydroxide in a polar solvent, removing water from the system, adding a dihalogenobenzenoid compound to the system and polycondensing the mixture. This aromatic polyether can be obtained by terminating the above aromatic polyether by using a monohydric phenol or a monohalogenobenzenoid compound as an terminating agent in the above reaction.

    Abstract: PURPOSE: A reticulate material that is produced by crosslinking a net-work of a polymer mainly composed of poly-ε-caprolactone, thus being suitably used as fixing material for plaster casts, because the network is not deformed even near the melting point of the polycaprolactone but easily softens at low temperature.
    CONSTITUTION: The objective reticulate material is composed of a polymer mainly consisting of poly-ε-caprolactone and crosslinked. The poly-ε-caprolactone has number-average molecular weight of 5,000W200,000, preferably of 10,000W100,000. A combination of extrusion into cylindrical networks with crosslinking by irradiation with UV or EB is advantageous. The above-stated polymer is obtained by the polymerization of ε-caprolactone in the presence of a catalyst at 120W220°C for a few hours by using a compound bearing hydroxyls on its both terminals such as polyethylene glycol of more than 300 molecular weight as a polymerization initiator.

    Abstract: PURPOSE:To carry out the purification and separation of a polymer having low residual solvent content, uniform particle size and high bulk density, in high efficiency by cooling an aromatic polyether polymer mixture to form a precipitate, granulating the precipitate and removing by-products and reaction solvent from the granule. CONSTITUTION:A mixture composed of an aromatic polyether polymer, by- products (e.g., KCI) and reaction solvent (e.g., tetramethylene sulfone) is cooled to a temperature near the freezing point of the reaction solvent and the produced precipitate is granulated. The objective aromatic polyether polymer can be separated in purified state by removing the by-products and the reaction solvent from the granule. The obtained polymer has excellent heat-resistance and flame-retardance and is useful as a resin for the parts of electronic apparatus.
