At present, it is of great significance to develop an effective method of recycling cyclic olefin copolymers (rCOC) due to its increasing application. But, its poor toughness is still an important difficulty to limit its effective recycling. In this article, we introduced PA6 into the POE-g-MAH/rCOC composites. Because of the good compatibility of POE-g-MAH between PA6 and rCOC, it just led to an overall improvement in mech. properties of PA6/POE-g-MAH/rCOC (45/15/40) composites. Its tensile strength reached 42.3 MPa, which was more than 41.9% compared with that of POE-g-MAH/rCOC composites. Its notched impact strength was 11.7 kJ/m2, which was higher than 875.0% compared with rCOC. Furthermore, the component of PA6 was wrapped by nonpolar rCOC and POE-g-MAH, resulting in a low water absorption rate (1.0%). So, the strength of the composites only dropped a little after water adsorption. In summary, the addition of PA6 helped the composites effectively utilize the toughness of POE-g-MAH. Thus, we developed an easy method to recycle rCOC and prepare the responding composites with high strength and toughness.
