Title:
LIQUID CRYSTAL POLYESTER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2017/114162
Kind Code:
A1
Abstract:
Disclosed is a liquid crystal polyester composition, comprising the following components in parts by weight: 100 parts of a liquid crystal polyester and 5-100 parts of a fibrous filler; and the weight content of 4-hydroxyacetophenone is 0.5 ppm to 550 ppm based on the total weight of the liquid crystal polyester composition. According to the present invention, by selecting and using 4-hydroxyacetophenone for adding to a liquid crystal polyester composition formulation in a content of 0.5 ppm to 550 ppm based on the total weight of the liquid crystal polyester composition, the heat-resistant stability of the obtained liquid crystal polyester composition at high temperatures is significantly improved unexpectedly, the liquidity thereof is also improved, and the other aspects of the performances of the liquid crystal polyester composition are not influenced.
