| Abstract: | A novel imide modified vinyl‐containing fluorosilicone resin (MP‐VFS) was firstly prepared from maleopimaric acid (MPA), and characterized by 1H NMR and 13C NMR. Containing MPA based imide heterocycle (MPABI), MP‐VFS was further used as a novel cross‐linker to prepare MPA modified fluorosilicone rubber (MP‐FSR). Morphology, mechanical and oil‐resistance properties, thermal properties, and low temperature resistance of MP‐FSR had been studied. Microphase separation was observed in MP‐FSR. Although the tensile strength of fluorosilicone rubber was not significantly enhanced, the tearing strength, breaking elongation, rebound resilience and hardness were effectively improved. When the MP‐VFS content was 2.0 wt %, the tearing strength of MP‐FSR was increased by 23.5%, breaking elongation by 18.6% and rebound resilience by 9.7%. The thermal stability was enhanced due to the incorporation of MPABI. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015 , 53, 1769–1776 |
