Abstract:
A polyester blend comprising:(a) one or more liquid crystalline polyesters derived from:(1) diacid residues consisting essentially of:(a) about 3.8 to 20 mole percent terephthalic acid (T) residues, and(b) about 15 to 31 mole percent 2,6-naphthalenedicarboxylic acid(N);(2) diol residues consisting essentially of:(c) about 25 to 40 mole percent hydroquinone (HQ) residues; and(d) about 20 to 51 mole percent p-hydroxybenzoic acid (PHB) residues,wherein the T/T+N molar ratio is from about 15:85 and 50:50, the moles of HQ are equal to the sum of the moles of T+N, and the total of the (a), (b), (c), and (d) mole percentages is equal to 100, andthe liquid crystalline polyester has a melting point determined by differential scanning calorimetry equal to or less than 360.degree. C., and(b) talc.
