【摘要】 用对苯二甲酸二甲酯（ＤＭＴ）、乙二醇（ＥＧ）和带有－ＯＨ、－ＮＨ２等活性基团的染料和颜料为聚合单体，通过熔融缩聚法合成了几种自着色聚酯色素，测定了聚酯色素中色素的含量，并对合成过程和聚酯色素的性质进行了研究。结果表明，染料和颜料的结构与用量对聚酯色素的合成和性质有重要的影响。更多还原

【Abstract】 The some self colored polyesters using colorants with OH, NH 2 groups as the third monomer have been synthesized. The contents of incorporated colorant in self colored polyesters were deterimined. Studies on both synthesizing processes and properties of self colored polyesters reveal that along with an increase of colorant using in reactions both the intrinsic viscosity and the propagation rate of self colored polyester decrease. DSC thermograms of self colored polyesters show that the melting point of self colored polyesters is lower than that of PET and there are no obvious glass transitions( T g). Moreover, the solubility of colorants has been greatly improved as they were incorporated into the chain of polyester. The products were determined by IR, UV, DSC, TGA. The effects of temperature on polymerization was also discussed.更多还原
