以转基因大豆油（TSO）为增塑剂，制备三元乙丙橡胶（EPDM）胶料。为了比较，用石油基石蜡油（PO）制备了类似的化合物，PO是EPDM最常用的增塑剂之一。用门尼粘度计、毛细管流变仪、差示扫描量热仪（DSC）和橡胶加工分析仪（RPA）研究了TSO和PO的增塑作用。结果表明，TSO对EPDM的增塑效果优于PO。研究了EPDM胶料的硫化特性。发现TSO在固化过程中与固化剂过氧化二异丙苯（DCP）反应。过量的TSO导致低交联密度，这是通过调整DCP的加入量来改善。比较了不同用量TSO和PO增塑EPDM硫化胶的力学性能、耐抽提性和热稳定性，确定了TSO替代PO的最佳用量。在增塑剂用量相同且不超过15份的条件下，TSO增塑EPDM硫化胶的拉伸强度、撕裂强度、扯断伸长率、耐拔出性和热稳定性均高于PO增塑EPDM硫化胶，但海岸A硬度低于PO增塑EPDM硫化胶。© 2013威利期刊公司.

Ethylene propylene diene monomer (EPDM) compounds were prepared with different amounts of transgenic soybean oil (TSO), a renewable and reactive plasticizer. For comparison, similar compounds were prepared with petroleum-based paraffin oil (PO), one of the most common plasticizers for EPDM. The plasticization effects of TSO and of PO were studied by Mooney viscometry, capillary rheometry, differential scanning calorimetry (DSC), and rubber processing analysis (RPA). The results showed that TSO has better plasticization effect than PO on EPDM. In addition, the curing characteristics of the EPDM compounds were studied. TSO was found to react with the curing agent dicumyl peroxide (DCP) during the curing process. Excessive amounts of TSO led to low crosslinking density, which was improved by adjusting the added amount of DCP. The mechanical properties, extraction resistance, and thermal stability of the EPDM vulcanizates plasticized with different amounts of TSO and PO were compared to determine the optimum amount of TSO to replace PO. At the same amount and no more than 15 phr of plasticizer, the TSO-plasticized EPDM vulcanizate has higher tensile and tear strength, elongation at break, extraction resistance, and thermal stability, but lower Shore A hardness than the PO-plasticized EPDM vulcanizate. © 2013 Wiley Periodicals, Inc.
