Abstract In this study, the novel ladder polymer (NLP) was syntheriszed and used as flame-reatardant additive for vinyl ester resin (VER). Two kinds of silane coupling agent was ultilized for fabrication of nLP then its characteristics were confirmed with help of nuclear magnetic resonance, Fourier transform infrared spectroscopy, X-ray diffractometry. The NLP based composites were fabricated at room temperature using the metyl etyl keton peroxide as a starter. Many characteristics of fabricated composites were examined as mechanical properties, the compatibility, flame retardant behaviours. The experimental results indicated that the VER with presence of 20 wt.% of NLP (S3 sample) have flexural strength, flexural modulus increased by195.6%, 260.6%, respectively. Moreover, this sample also exhibited the decreasing in total smoke release (TSR), and peak heat release rate (PHRR) was about 20.7%, and 52.2%, respectively. These results indicated that the NLP is the good candidate for simultaneous improvement of mechanical properties and flame retardant of VER.

苯基/乙烯基聚倍半硅氧烷基梯形聚合物作为乙烯基酯树脂的新型添加剂：制造、机械和阻燃性能

摘要 本研究合成了新型梯形聚合物（NLP），并将其用作乙烯基酯树脂（VER）的阻燃添加剂。将两种硅烷偶联剂用于制备nLP，并通过核磁共振、傅里叶变换红外光谱、X射线衍射等手段对其特性进行了确认。使用过氧化甲基乙基酮作为起始剂在室温下制造基于 NLP 的复合材料。检查了制造复合材料的许多特性，如机械性能、相容性、阻燃行为。实验结果表明，含有20 wt.% NLP的VER（S3样品）的弯曲强度、弯曲模量分别增加了195.6%、260.6%。此外，该样品还表现出总烟雾释放量 (TSR) 的降低，和峰值放热率 (PHRR) 分别约为 20.7% 和 52.2%。这些结果表明，NLP 是同时提高 VER 的机械性能和阻燃性的良好候选者。
