Estimating the term…
Polyolefin molding compositions and molded articles thereof exhibit exceptional mechanical strength, dimensional accuracy and heat deformation characteristics and are provided by melt-blending a polyolefin base resin, a liquid-crystal polyester resin, and a filler material. The liquid-crystal polyester is one which exhibits optical anisotropic characteristics in the melt-phase and preferably has a melt-viscosity of 20000 to 50 Poise as determined at a temperature of 310.degree. C. and a shear rate of 1200 sec.sup.-1. The liquid-crystal polyester resin forms a three-dimensional network structure throughout the polyolefin base resin and envelops substantially all of the filler material therewithin. As a result, the molded articles of the polyolefin compositions can be employed in end-use applications which require improved mechanical strength, dimensional accuracy and/or heat deformation characteristics.
