    摘要: A heat-resistant polyamide polymer having melt-moldability is obtained by reacting an aromatic diamine having the general formula: ##STR1## with an equivalent amount of aromatic dicarboxylic acid dihalide in an organic solvent in the presence of an aqueous solution of an alkali-metal hydroxide. When an equimolar mixture of terephthalic acid dihalide and isophthalic dihalide is reacted with the diamine, polyamide polymers with good melt-moldability are obtained.
