Abstract: PURPOSE:To obtain a liq. crystal polyester resin compsn. with small mechanical anisotropy by compounding a liq. crystal polyester resin forming a specified anisotropic molten phase with a specified silane-contg. compd. CONSTITUTION:A liq. crystal polyester resin compsn. prepd. by compounding 100 pts.wt. liq. crystal polyester resin (A) which consists of the repeating units of formulas I, II and IV or I, II, III and IV and forms an anisotropic molten phase, 0-200 pts.wt. filler (B) and 0.01-20 pts.wt. silane-contg. compd. of formula V. In the formulas, R1 is a group of formula VI, etc., and R2 is a group of formula VII, etc. In addition, the structural unit of formula IV is equimolar with the structural unit of formulas (II+III). Examples of the filler induce glass fibers, ceramic fibers, metal fibers, carbon fiber, clay and titanium oxide. As the compsn. exhibits small mechanical anisotropy, it can be used for various purposes where dimensional accuracy is required, such as electric and electronic parts.
