内容記述
Crosslinking structures were formed in electron-beam-irradiated polyamide11 (PA11), without and with triallyl isocyanurate (TAIC). The gel fractions of PA11 without TAIC steeply increased when irradiated with an electron beam of above 190 kGy and saturated to 76.2% when the dose was higher than 750 kGy. PA11 was determined to be a radiation crosslinking-type polymer. TAIC was found to promote the induction of crosslinking of PA11 main chains. PA11 formed a network structure in 3 phr (per hundred resin) TAIC with an electron beam of 10 kGy. The crosslinked PA11 had higher thermal stability, as demonstrated by the retention of its original shape at temperatures even higher than 200 °C.
