POLYPHENYLENE ETHER MELT EXTRUSION FORMED BODY AND METHOD FOR PRODUCING POLYPHENYLENE ETHER MELT EXTRUSION FORMED BODY
An object of the present invention is to provide a polyphenylene ether melt extrusion formed body which can be obtained by melt forming without mixing other resin components and has excellent properties such as mechanical strength, and a method for producing the same. The present invention relates to a polyphenylene ether melt extrusion formed body comprising a polyphenylene ether component which has a rearrangement structure having a continuous structure bonded at an ortho-position in a repeating unit continuously bonded at a para-position.
AMORPHOUS EPOXY FIBER, FIBER STRUCTURE, AND MOLDED BODY
Provided is an amorphous epoxy fiber excellent in dimensional stability, a fiber structure comprising at least in part amorphous epoxy fibers, and a molded body formed by melting said fibers. The amorphous epoxy fiber has a birefringence value of 0.005 or lower. For example, the amorphous epoxy fiber may include an amorphous epoxy resin represented by the following general formula:
##STR00001## in which, X is a residue of a bivalent phenol and n is 20 or greater (preferably 20 to 300, more preferably 40 to 280, still more preferably 50 to 250). The amorphous epoxy fiber may have an average fiber diameter of single fibers of 40 μm or smaller.

Odour control material, method for preparation of an odour control material and an absorbent product comprising the odour control material
The present invention relates to an odor control material consisting of a water-insoluble particulate odor control agent and a thermoplastic water-soluble carrier matrix encapsulating the odor control agent. The carrier matrix dissolves when in contact with an aqueous solution, such as urine and the odor control material is obtained by means of thermoforming. The invention relates also to a method for the preparation of the odor control material and the use of the odor control material in absorbent products. The present odor control material minimizes dusting problems caused by particulate odor control agents in production processes.
