Abstract
Some oxygen containing groups (mainly carbonyl group) are introduced onto the molecular chains of styrene-b-(ethylene-co-1-butene)-b-styrene triblock copolymer (SEBS) through ozone treatment, so as to improve the interface compatibility between PA6 and SEBS. With increasing ozonised SEBS content, toughness of the PA6/SEBS blend is increased. Compared with PA6/SEBS blend (80: 20), the impact strength of PA6/ozonised SEBS (80: 20) blend is increased from 21·5 to 68·7 kJ m−2.
