马来酸酐官能化ASA对PA6的增韧研究
Toughening of PA6 with MAH Functionalized Acrylate- styrene-acrylonitrile Copolymer
摘要
Abstract
Maleic anhydride (MAH) functionalized acrylate-styrene-acrylonitrile (ASA) copolymers (ASA-g-MAH) were prepared via an emulsion polymerization, and were used to toughen polyamide6(PA6). Molau tests showed that some reactions between PA6 and ASA-g-MAH had taken place. The effect of MAH content on mechanical properties of PA6/ASA-g-MAH blends were studied. The mechanical properties of PA6/ASA-g-MAH blends increased with increasing MAH content. When MAH content was 4 ~//00, notched impact strength of the blend reached 1008 J/m. Compared with the PA6/ASA blends, the PAf/ASA-g-MAH blends had higher tensile strength and elongation at break. Scanning electron microscopy (SEM) showed ASA particles dispersed in the PA6 matrix uniformly when MAH content was 4 %. The cavitation of rubber particles and shear yielding of the PA6 matrix were the major toughening mechanisms.关键词
