| 摘 要： | 使用双酚A型氰酸酯(BADCy)的三聚体Tri-mer-60作为扩链剂,与BADCy单体进行对比,对聚苯二甲酸乙二醇酯(PET)进行扩链.通过比较扩链后的PET的熔体扭矩,发现三聚体对PET的扩链效果优于单体.并研究了不同含量的Tri-mer-60对PET的扭矩、特性黏度、羧基含量、流变性能以及结晶性能的影响.结果表明:随着Tri-mer-60含量的增加,扩链反应速度增加,PET的特性黏度增加,羧基含量降低.扩链反应的发生改善了PET的流变性能,但阻碍了PET的结晶. |

| Abstract: | The tri-mer of BADCy through cyclotrimerization was studied as chain extender for PET and the effects of chain extension was compared with BADCy monomer.With a fraction of BADCy tri-mer in the chain extender,the modified PET exhibited higher melt torque than that modified BADCy monomer alone.With increasing amount of Tri-mer-60 introduced,the modified PET gave rise to higher torque,higher intrinsic viscosity,lower melt index(MI) and higher dynamic viscosity.DSC analysis represented that Tm and Tc of the mod... |
