摘要
采用接枝改性淀粉作为LLDPE/淀粉共混体系增容剂,对其单体作用和与接枝改性PE配合作用的增容效果进行了研究,发现配合作用增容效果比较明显,体系拉伸强度可达9.77MPa,伸长率为128％,并在此基础上进一步考察了偶联淀粉与LLDPE共混的效果。
The influence of starch graft copolymers as the compatilizer in the biodegradable blends of LLDPE/starch on the mechanical properties has been investigated in this paper. It has been found that the synergism of S -g -PEA and graft modified LLDPE has the advantage over the function of sole S -g-PEA in improving compatibility. The tensile strength of the blend system investigated has attained to 9. 77MPa while the elongation is kept around 128%. The compatibility of the blend of LLDPE and coupling treated starch has also been examined and no obvious improvement has been found.
