TAIC应用 Application of TAICA. 助交联剂 Crosslinking Coagent
TAIC作为过氧化物交联或自由基反应交联的助交联剂被广泛应用，如氯化聚乙烯（CPE)，EPDM，氟橡胶等等。
TAIC is widely used as a coagent for peroxide crosslinking or radiation crosslinking of Chlorinated Polyethylene (CPE), EPDM, Fluroelaster and so on.
1) 聚烯烃 Polyolefines
TAIC可以应用在聚烯烃的X射线等，或紫外线辐照交联中，可赋于聚烯烃较好的溶剂耐受性，同时较高温度时的强度也得到提高。
TAIC is availavle for linking by x-ray, y-ray electron or ultra violet ray radiation and the product polyolefines have the superior insolubility to solvents and the tensile strength at high temperature could be improved.
2) 氯化聚乙烯 Chlorinated Polyethylene (CPE)
TAIC可以通过提高CPE过氧化物硫化体系交联密度来有效的改善耐热性能。
TAIC is effective modifier to heat resistance with increasing of crosslinking density for peroxide crosslinking denisty for peroxide crosslinking of CPE. Since TAIC acts as an acceptor of HCI which is envolved from CPE at crosslinking reaction and deterioriates its physical properties.
3) 乙烯醋酸乙烯共聚物 Ethylene Vinyl Acetate Copolymer (EVA)
TAIC是EVA的最有效的助交联剂。不同的助交联剂在EVA过氧化物交联中作用顺序如下：
TAIC is the most effective coagent for crosslinking EVA. The effectivness of crosslinking coagent which acts in peroxide crosslinking of EVA is as follows;
TAIC = TAC > DVB => TMPTMA = DAP = EGDM > NON
TAIC: Triallyl isocyanurate
TAC: Triallyl cyanurate
DVB: Divinyl Benzen
TMPTMA: Trimethylolpropane trimethacrylate
DAP: Diallyl phthalate
EGDM: Ethyleneglycol dimethacrylate
NON: None of crosslinking coagent
4) 三元乙丙橡胶 EPDM
TAIC preferably contributes to promote crosslinking rate and also to improve its heat resistance, compression set and abrasion resistance
举例在过氧化物硫化体系中，加入助交联剂TAC或TAIC会使硫化的焦烧时间略为延迟，随着硫化时间的延长，助交联剂出现明显的促进交联效应。可能因为在硫化反应的初期阶段，助交联剂分子自身发生环化聚合，并与橡胶分子接枝而消耗部分橡胶分子自由基，此些自由基在无助交联剂时本应产生正常的化学交联。随着硫化时间的延长，烯丙基的双键与橡胶发生交联反应占主导地位，形成活性剂桥键，从而提高了交联效率。TAC与TAIC硫化效果的差别取决于分子活性有所不同，由于结构相似，对硫化影响差别并不明显[4]。
