In this work a novel sucrose based polyfunctional monomer (SPF) was prepared and evaluated as a co-agent in the radiation crosslinking of Ethylene propylene diene methylene linkage rubber (EPDM). The incroporation of SPF boosted the crosslink density which is reflected postively on the gel content and swelling resistance of irradiated EPDM. The mechnical properties of EPDM enhanced as the SPF content increased where the highst tensile strength and elastic modulus were recorded for EPDM which contains 5 phr of SPF. In addition, a decrease in the dielectric constant and an increase in the electrical resistivity of EPDM were observed as SPF content increases. The thermal stability of EPDM was improved after the addition of SPF, especially at temeperature lower than 400 °C.

在这项工作中，制备了一种新型蔗糖基多官能单体 (SPF)，并对其作为三元乙丙橡胶 (EPDM) 辐射交联中的助剂进行了评估。SPF的加入提高了交联密度，这对辐照EPDM的凝胶含量和抗溶胀性有积极的反映。EPDM 的机械性能随着 SPF 含量的增加而增强，其中记录了含有 5 份 SPF 的 EPDM 的最高拉伸强度和弹性模量。此外，随着 SPF 含量的增加，观察到 EPDM 的介电常数降低和电阻率增加。添加 SPF 后，EPDM 的热稳定性得到改善，尤其是在低于 400 °C 的温度下。
