| Abstract: | In the present paper the gel formation of polyamide 610 by γ-ray irradiation in the presence of polyfunctional monomer and γ-crystal nucleating agent under vacuum or air atmosphere had been studied. It was found that the gel formation was dependent on the content of polyfunctional monomer and nucleating agent. However, there was very little difference between gel contents irradiated under vacuum and air atmosphere. The results showed that the crosslinking by γ-irradiation enhanced the mechanical properties of PA610 especially at high temperature in the presence of polyfunctional monomer and γ-crystal nucleating agent. The mechanism of radiation crosslinking and scission was discussed according to the composition and quantity of gas released from three kinds of PA during irradiation. |
