摘要：
In this study, the effect of electron beam irradiation on the thermal and mechanical properties of ternary polyamide copolymer (tPA) was investigated. The crosslinking of tPA induced by e-beam irradiation was carried out over a range of dose from 50 to 300 kGy with triallyl cyanurate (TAC), triallyl isocyanurate (TAIC), and N,N'-m-phenylene dismaleimide (HVA-2) as crosslinking co-agents. With increasing dose, the gel contents of tPA containing the co-agents increased more significantly than neat tPA. After the addition of 2.5 phr HVA-2 into tPA and the electron beam irradiation of 150 kGy, the gel content of tPA increased from 11% to 77%, which has a profound influence on the tensile strength, glass transition temperature, and thermal stability of tPA.
