用电子束辐照聚酰胺11（PA 11），在不加和加三烯丙基异氰脲酸酯（TAIC）的情况下形成交联结构。不含TAIC的PA 11的凝胶分数在190 kGy以上急剧增加，并在高于750 kGy时饱和至76.2%。PA 11被确定为辐射交联型聚合物。发现TAIC促进PA 11主链的交联诱导。当TAIC用量为3份/100树脂，辐射剂量为10 kGy时，PA 11的网络结构得到了有效的形成。交联的PA 11增加了热稳定性，如在甚至高于200 °C的温度下保持其原始形状所证明的。
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.
