摘　　要：在有机化合物1,8-二氮杂二环十一碳-7-烯(DBU)或1,5,7-三氮杂二环[4.4.0]癸-5-烯(TBD)的催化作用下,通过嵌段共聚的方式引入ε-己内酯(CL),制备出PPDO-PCL-PPDO的三嵌段聚合物,实现了对聚对二氧环己酮(PPDO)改性的目的.所合成的共聚物具有可调节的亲水性、良好的稳定性、柔韧性和机械强度,显示出潜在的工业和生物医学应用前景.A triblock polymer of PPDO-PCL-PPDO was prepared by introducingε-CL through block copolymerization under the catalysis of organic compounds 1,8-diazabicycloundecen-7-ene(DBU)or 1,5,7-triazabicyclo [4.4.0]dec-5-ene(TBD),which realized the purpose of modifying PPDO.The prepared copolymers have advantages of adjustable hydrophilicity,stabilization,flexibility,and mechanical strength,showing potential industrial and biomedical application prospects.
