Description

technical field

[0001] The invention relates to the field of materials, in particular to a high-temperature-resistant nylon and a synthesis method thereof. Background technique

[0002] In recent years, in order to meet the higher performance requirements in the fields of electronics, electrical appliances, automobiles, etc., especially with the development of Surface Mount Technology (SMT), ordinary high-temperature-resistant engineering plastics polyphenylene sulfide (PPS) and The heat resistance of liquid crystal polymer (LCP) can no longer fully meet its requirements, so it is necessary to develop engineering plastics with higher heat resistance.

[0003] Semi-aromatic polyamides are usually prepared by polycondensation of aliphatic diamines or diacids and diacids or diamines with aromatic rings. Due to the introduction of aromatic rings into the main chain of the polyamide molecule, its heat resistance And the mechanical properties have been improved, and the water abs...
