| 摘 要：研究了PA6/SEBS和PA6/SEBS-g-MAH共混體系與PA6/SEBS/SEBS-g-MAH三元共混體系的力學(xué)性能與流變性能變化。結果表明,采用SEBS增韌尼龍6,控制SEBS和SEBS-g-MAH的比例,在SEBS總量為20%時(shí)能夠制得超韌性的尼龍6,缺口沖擊強度可達到90kJ/m2以上。PA6/SEBS表現出不相容共混體系的流變行為,PA6/SEBS-g-MAH共混體系高于共混物中任一組分的粘度,反映出共混后增強了兩相的界面相互作用。三元共混體系的粘度表現為SEBS和SEBS-g-MAH共同作用結果。 |

| Abstract：Mechanical and rheological properties have been investigated of PA6/SEBS blends ,PA6/SEBS-g-MAH blends and PA6/SEBS/SEBS-g-MAH blends in this paper. The results showed that touchening PA6 is available and the impact strength was above 90 KJ/m2 when the total amount of SEBS is 20% adopting SEBS modifying PA6.PA6/SEBS blends act as imcompatibility rheology ,PA6/SEBS-g-MAH have the highest viscosity among the blends,the action of interphase is strengthened after blending.Viscosity of PA6/SEBS/SEBS-g-MAH is the... |
