A SEMIAROMATIC POLYAMIDE AND THE PREPARATION METHOD THEREOF

摘要

A semiaromatic polyamide and the preparation method thereof. The semiaromatic polyamide of the present invention is manufactured as follows: producing an amide salt of high purity by neutralization reaction of aromatic dicarboxylic acids and aliphatic diamines with 4-14 carbon atoms in an organic solvent; carrying out prepolymerization of the amide salt of high purity in the presence of water; and subjecting the resulted prepolymer to further polymerization.
