Effects of triallyl cyanurate (TAC) derivatives on the radiation crosslinking of polyethylene and thermal oxidation stability of the irradiated products were examined, The TAC derivatives used were N,N''-bis-(2,4-dialloxy-s-triazine-6)-diaminoethane (TED) and N,N''-bis-(2,4-dialloxy-s-triazine-6)-piperazine (TP). The addition of these polyfunctional monomers increased the degree of crosslinking of polyethylene in the order of TP>TAC>TED. The oxidation stability of thus crosslinked polyethylene was influenced by both its degree of crosslinking and the nature of additives. The additives examined increased the oxidation stability of the crosslinked polyethylene in the order of TP>TED>TAC.

폴리에틸렌을 감마선에 의하여 방사선 가교시킬 때 triallyl cyanurate (TAC) 유도체가 가교반응과 가교폴리에틸렌의 산화안정성에 미치는 영향을 검토하였다. 사용한 TAC 유도체는 N,N''-bis-(2,4-dialloxy-s-triazine-6)-diaminoethane (TED)과 N,N''-bis-(2,4-dialloxy-s-triazine-6)-piperazine (TP)이다. 이들 다기능성 단위체는 모두 TAC와 같이 가교촉진 효과가 있었으며 그순서는 TP>TAC>TED이었다. 가교폴리에틸렌의 산화 안정성은 가교도에 따라 향상되나 이들 첨가제에 의하여 더욱 증가하였으며 TP>TED>TAC순의 효과를 보였다.
