以二苯甲酮（BP）为光引发剂，三烯丙基异氰脲酸酯（TAIC）为交联剂，采用紫外光照射法对滑石粉、碳酸钙和玻璃球填充的伊娃共混物进行光交联。通过凝胶测定、热延伸试验、机械老化和热老化试验、紫外光谱和扫描电镜研究了影响交联过程和相关性能的各种因素。结果表明，在最佳条件下，填充25 phr无机填料的伊娃/滑石粉、伊娃/CaCO 3和伊娃/GB样品在5 sec紫外光照射下，凝胶含量可达70 wt%以上，这对于伊娃共混材料的某些应用是足够的。交联速率和最终凝胶含量的顺序为伊娃/GB >伊娃/滑石粉>伊娃/CaCO 3。力学和热老化试验结果表明，光交联伊娃/滑石粉、伊娃/CaCO 3和伊娃/GB样品的拉伸强度和热老化性能明显优于未光交联样品。版权所有© 2009约翰威利父子有限公司。
The blends of EVA filled with talc, calcium carbonate, and glass ball (GB) have been photocrosslinked by UV irradiation in the presence of benzophenone (BP) as a photoinitiator and triallyl isocyanurate (TAIC) as a crosslinker. The various factors affecting the crosslinking process and the related properties have been studied by gel determination, heat extension test, mechanical and thermal aging test, UV spectroscopy, and scanning electron microscopy. The results show that the EVA/talc, EVA/CaCO3, and EVA/GB samples of 1 mm thickness filled with 25 phr inorganic filler can be photocrosslinked to gel content of above 70 wt% by 5 sec UV-irradiation under optimum conditions, which is sufficient for some applications of EVA blend materials. The crosslinking rate and final gel content level are in the order of EVA/GB > EVA/talc > EVA/CaCO3. The data from mechanical and thermal aging tests give evidence that the photocrosslinked EVA/talc, EVA/CaCO3, and EVA/GB samples are of much better tensile strength and thermal aging properties than those of the unphotocrosslinked ones.
