摘要:Provided is a semi-aromatic polyamide, comprising, on the basis of the molar content of all repeating units, the following repeating units: 46‑54 mol% of 10T unit derived from 1,10‑diaminodecane and terephthalic acid, 46-54 mol% derived from one or more monomers in diacid Y containing 4-36 carbon atoms, and XY unit consisting of one or more monomers in diamine X containing 4-36 carbon atoms; the 10T unit and XY unit in the semi-aromatic polyamide chain segment are arranged in an alternating order ... 10TXY10TXY10TXY 10TXY10TXY ...; the semi-aromatic polyamide at least contains three monomers. In the semi-aromatic polyamide prepared by means of the special preparation method, 10T and XY units are arranged alternately, and in comparison with ordinary random copolymerized semi-aromatic polyamides, it has higher crystallinity and a higher melting point, and the water absorption rate is low.
