THE REINFORCING AND TOUGHENING OF NYLON 11/NYLON 6 BLENDS BY DENDRIMER

Blends of nylon 11/nylon 6 were prepared in the presence of 4.0 generation polyamidoamine dendrimer as compatibilizer. By the change of PAMAM content, the influence on mechanical properties was investigated. The results indicate that the addition of polyamidoamine dendrimer brings about an improvement on the characteristics of nylon 11/nylon 6 blends. Under the circumstance of adding 0.25% PAMAM dendrimer, the tensile strength and tensile elongation of the blend were increased. Meanwhile, the Izod impact energy was also slightly increased.
