| 摘 要： | 以扩链剂2,2 双(2 噁唑啉)(BOZ)与苯酐(PA)联用改性回收PET,系统地考察了增黏改性后回收PET动态流变性能和动态力学性能的影响。结果表明,BOZ与PA联用的改性效果明显优于单用BOZ改性回收PET体系;但因扩链剂的加入,在PET分子链中引入的柔性链段而导致聚合物弹性模量下降。

| Abstract: | The dynamic rheological behavior and dynamic mechanical property were investigated when 2,2-bis (2-oxazoline) (BOZ) and phthalic anhydride (PA) were simultaneously incorporated into recycled PET.The results displayed that there was a very remarkable improvement in the systems with the composite coupler compared to that material with BOZ.The addition of the chain-extenders would introduce the flexible segments into recycled PET and resulted in lower modulus of the plastics. |
