<p>The invention provides an inexpensive liquid-crystal polyester resin composition which can be injected or extruded to give moldings which are excellent in heat resistance, processability, and mechanical properties, in particular, weld strength and impact resistance, and which have excellent properties even when they are thin-wall ones, and a process for producing the composition. (1) A liquid-crystal polyester resin composition comprising 100 parts by weight of a composition consisting of 1-99 wt.% of a liquid-crystal polyester (A) and 99-1 wt.% of an aromatic polycarbonate and 0.001-3 parts by weight of a diamine; and a process for producing the same by melt kneading the polyester, the polycarbonate and the diamine. (2) A liquid-crystal polyester resin composition which comprises a liquid-crystal polyester (A), an aromatic polycarbonate (B), a diamine (C), and non-surface-treated glass fibers (D) having a number-average fiber diameter of 5-25 νm, a number-average fiber length of 30-1,000 νm and a ratio of the number-average fiber length to the number-average fiber diameter of 2 to 150, and wherein the ratio of the weight percentage of component (A) to that of component (B) is 35-99 to 65-1 and the contents of components (C) and (D) are 0.0001-3 parts by weight and 1-100 parts by weight, respectively, based on 100 parts by weight in total of components (A) and (B).</p> |
