Abstract 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 above the dose of 190 kGy, and saturated to 76.2% at higher than 750 kGy. PA11 was ascertained as a radiation crosslinking type polymer. TAIC was found to promote the induction of crosslinking of PA11 main chains. The network structure of PA11 was effectively formed in 3 phr (per hundred resin) TAIC at the dose of 10 kGy. The crosslinked PA11 increased the thermal stability, as demonstrated by retention of its original shape at temperatures even higher than 200 °C.
