Tablets of thermoplastic resin and filler, in which the compositional ratio of the two is so controlled that the thermoplastic resin accounts for from 1 to 40% by volume and the filler for from 60 to 99% by volume based on the sum of the two, 100% by volume, are obtained by compression-molding thermoplastic resin powder and filler into the tablets, or melt-kneading thermoplastic resin and filler followed by compression-molding the powder of the resulting composition into the tablets. The filler content thereof is high, heretofore unknown in the art, and the tablets efficiently exhibit the properties of the filler therein.

Disclosed are a liquid-crystalline resin composition comprising (A) from 20 to 99 parts by weight of a liquid-crystalline resin and (B) from 1 to 80 parts by weight of aluminium borate whiskers of which the grain size distribution as obtained through laser diffractometry is such that D90/D10 is from 7.5 to 20, and precision moldings of the composition.

Liquid-crystalline resin composition and precision moldings of the

A polyamide resin composition comprising 100 parts by weight of a polyamide resin, from 0.01 to 100 parts by weight of a liquid-crystalline resin, and from 0.01 to 5 parts by weight of an acid anhydride all the time has good fluidity even when it is left for a relatively long period of residence time in a cylinder of a molding machine while it is molded, and has good moldability. The amount of cushion resin needed for molding the composition fluctuates little, and the failure such as cobwebbing in molding the composition is reduced. The moldings of the composition have good impact resistance and good outward appearance. The composition is most suitable to producing box-type moldings with thin-wall parts.

Polyamide resin composition

Liquid-crystalline resin compositions and moldings

A liquid-crystalline resin with ester bonds, which has a hydroxyl terminal concentration of not smaller than 15.times.10.sup.-6 equivalents/g, and a thermoplastic resin composition comprising the liquid-crystalline resin.

Liquid-crystalline resin and thermoplastic resin composition

A liquid crystalline resin which comprises at least one kind of liquid crystalline polymer selected from liquid crystalline polyester and liquid crystalline polyester amide, both forming an anisotropic molten phase, and an inorganic phosphorus compound, said liquid crystalline resin having an absorbance of 0.5 or less at 380 nm when measured over an optical path length of 10 mm in a 0.5 wt % solution in a 1:1 mixed solvent of pentafluorophenol and chloroform (by weight). It is useful as engineering plastics because of improved color, heat resistance, and hydrolytic resistance.

Liquid crystalline resin and molded product thereof

A polyoxymethylene multi-copolymer obtainable by copolymerizing
