Abstract: PROBLEM TO BE SOLVED: To obtain a composition for a partly or wholly cylindrical molding excellent in dimensional stability and surface appearance as well as mechanical properties and heat resistance by selecting a composition prepared by mixing a polyethylene terephthalate resin with glass fibers, an inorganic layered compound and a polyfunctional compound in a specified ratio so that the mean particle diameter of the inorganic layered compound in the composition may fall within a specified range. SOLUTION: This composition is one which comprises 100 pts.wt. polyethylene terephthalate resin, 20-100 pts.wt. glass fibers, 1-10 pts.wt. inorganic layered compound and 0.1-5 pts.wt. polyfunctional compound and in which the mean particle diameter of the inorganic layered compound falls within the range of 0.05-3 μm. The inorganic layered compound is desirably one having hydroxyl groups on the end portions of the layers or one having ion exchange capacity. The polyfunctional compound is exemplified by an epoxysilane, a compound having at least two functional groups such as epoxy groups or isocyanato groups or a carboxylic acid anhydride. This composition can exhibit its effect especially when it is processed by injection molding.

Abstract: PROBLEM TO BE SOLVED: To improve the mechanical characteristics, hydrolyzability and moldability by blending a polybutylene terephthalate, reinforcing fibers and an epoxy compound so that the reinforcing fibers in the composition have a specified relation between the weight-mean fiber length and the fiber diameter and a specified ratio of the weight-mean fiber length to the number-mean fiber length. SOLUTION: The polybutylene terephthalate (A) is obtained by the polycondensation of the principal constituents comprising terephthalic acid or its ester-forming derivative, and 1,4-butane diol and its ester-forming derivative. The reinforcing fibers (B) comprise those usually used for reinforcing a resin, and having a diameter of 4-25μm. The relation between the weight-mean fiber length(Lw) to the diameter-(d), in terms of the ratio Lw/d, is (50-250):1, and the ratio of the Lw to the number-mean fiber length (Ln), (Lw/Ln), is (1.1 to 3.5):1, preferably (1/1 to 2.0):1. The amount of component B blended is 1-60wt.% based on the total of components A and B. The epoxy compound (C) is blended in an amount of at most 2.5 pts.wt. based on 100 pts.wt. total of components A and B.

CONSTITUTION:A drum has disks, each of which has a hole 1 having the same shape and size as those of the hollow part of a circular column, is respectively fixed concentric to the hole 1 to each of the both ends of the hollow circular column and is provided respectively with eight holes 1 under the condition that a through hole 2 consists of both disks and the circular colmn. Extrusion- molded article made of water-crosslinkable silane-modified polyolefin composition is taken up to the drum. The article taken up to the drum is water- crosslinked in a worn water tank. As the water-crosslinkable silane-modified polyolefin, silane copolymerized polyolefin, silane graft polyplefin or the like is preferably used. The silane copolymerized polyolefin is the copolymer of ethylene and ethylenically unsaturated silane comnpound.
