[中文文摘]研究了偶联剂对淀粉的物理改性 ,改性淀粉加入量对填充 PE塑料体系相态结构、力学性能的影响 ,认为偶联剂的加入量大于淀粉含量的 1.0 %时 ,可获得具有较好的对 L L DPE掺混性的疏水化改性淀粉 ;提出了物理改性淀粉、增容剂等填充 PE塑料多组份共混体系的“夹心面包”模型和Al3 + 与淀粉间的配位络合物模型.[英文文摘]Physical modification with coupling agent of starch and the effect of the content of the modified starch on the phase structures and the mechanical properties of PE Plastics filled with starch was studied.It is suggested that the hydrophobic modified starch in the nature of good compatibility with L LDPE can be obtained when the amountof coupling agent is more the1 .0% .The layer bread model of the multicomponent blended system of PE plastics filled with physical modified starch,compatilizer and so on, and the coordination complex model between Al3+ and Starch were proposed
