LIQUID-CRYSTAL POLYESTER RESIN

摘要

The present invention provides a liquid-crystalline polyester resin, essentially consisting of the repeating units represented by formulae [I]-[IV]:
wherein p, q, r and s satisfy the following formulae: 0.4 ‰¦ p/q ‰¦ 2.0, 2 ‰¦ r ‰¦ 15, 2 ‰¦ s ‰¦ 15, and p+q+r+s = 100, provided that the liquid-crystalline polyester resin has a melting point of 190-250°C determined by differential scanning calorimetry. The liquid-crystalline polyester resin of the present invention exhibits a good molding processability at low temperatures and excellent mechanical properties.
