GMA grafting EPDM is prepared in Haake rheometer, and the effects of monomer and DCP contents on the grafting ratio are studied. The results show that the grafting ratio increases with increasing DCP content, and it reaches a balanced value when GMA content increases. The brittle tough transition is effected by the temperature and EPDM-g-GMA content, and the brittle tough transition temperature decreases by increasing EPDM-g-GMA content.
