Title:
LIQUID CRYSTAL POLYESTER RESIN
Document Type and Number:
WIPO Patent Application WO/2020/070904
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a liquid crystal polyester resin which exhibits excellent mechanical properties and suppresses blistering at the time of reflow. The present invention pertains to a liquid crystal polyester resin configured from repeating units represented by formulas (I)-(VII) [In the formula, p, q, r, s, t, u and v represent the compositional ratio (mol%) of each repeating unit in the liquid crystal polyester resin, and satisfy the following expressions: 15≤p≤30, 70≤q≤85, and 0.01≤r+s+t+u+v<2. Herein, the r, s, t, u and v are each at least 0 and less than 2, and an arbitrary two or more thereof are not 0].
