Poly(ethyl acrylate-co-methoxyethyl acrylate-co-dialkyl itaconate-co-vinyl chloroacetate)s (PEMDAVs) were synthesized by redox initiated emulsion polymerization of ethyl acrylate, methoxyethyl acrylate, vinyl chloroacetate, and biobased dialkyl itaconate as a modified monomer. The molecular weight of the synthesized PEMDAVs was in the range of 337 000 and 346 000 g/mol, which was higher than that of the unmodified polymer PEMV. The structure and thermal performance of PEMV and PEMDAVs was determined by ¹H nuclear magnetic resonance, differential scanning calorimetry, and thermogravimetric analysis. Carbon black (CB) was used as a filler to enhance the PEMV and PEMDAVs. Mechanical properties of PEMDAVs/CB nanocomposites got improved compared with PEMV/CB nanocomposite. In addition, we analyzed the effect of biobased monomer itaconate with different side chain length on the mechanical properties and oil resistance. It is worth noting that PEMDMV/CB with dimethyl itaconate content exhibited great heat oil resistance in ASTM #3 oil at 150 °C or even 175 °C. This work is expected to not only prepare excellent mechanical properties and oil-resistance elastomers but also provide some guidelines for the modified traditional rubber with biobased monomers.

生物基衣康酸酯改性丙烯酸纳米复合材料：机械性能、耐油性和耐热性

聚丙烯酸乙酯-共-丙烯酸甲氧基乙酯-共-衣康酸二烷基酯-共-氯乙酸乙烯酯（PEMDAVs）是通过丙烯酸乙酯、丙烯酸甲氧基乙酯、氯乙酸乙烯酯和生物基衣康酸二烷基酯作为改性单体的氧化还原引发乳液聚合合成的。合成的PEMDAVs的分子量在337 000和346 000 g/mol之间，高于未改性的聚合物PEMV。PEMV 和 PEMDAV 的结构和热性能由¹H核磁共振、差示扫描量热法和热重分析。炭黑 (CB) 用作增强 PEMV 和 PEMDAV 的填料。与PEMV/CB纳米复合材料相比，PEMDAVs/CB纳米复合材料的力学性能有所提高。此外，我们分析了不同侧链长度的生物基单体衣康酸酯对力学性能和耐油性的影响。值得注意的是，含有衣康酸二甲酯的 PEMDMV/CB 在 150 °C 甚至 175 °C 的 ASTM #3 油中表现出出色的耐热油性。这项工作不仅有望制备出优异的机械性能和耐油弹性体，而且为生物基单体改性传统橡胶提供一些指导。
