| titleOfInvention | Preparation method of PA (66-co-6T) copolymer |
| abstract | The invention relates to a preparation method of a PA (66-co-6T) copolymer, which comprises the following steps: preparing PA (66-co-6T) copolymer in a molten state by using hexamethylene diamine and an acid donor as polymerization monomers through a melt polycondensation reaction I, wherein the acid donor consists of terephthalic acid and adipic acid, and the molar percentage of the terephthalic acid in the acid donor is less than 60%. The invention unexpectedly finds that the PA (66-co-6T) copolymer can be prepared in a molten state by adjusting the content of the aromatic units, and the discharge is very convenient. |
