Imide‐containing vinyl fluorosilicone resin (MR‐VFS) was synthesized from maleated rosin (MR). And then, with MR‐VFS as a new polar cross‐linking agent in a heat curable fluorosilicone rubber composition, a series of maleated rosin‐modified fluorosilicone rubbers (MR‐FSR) were obtained. The effects of MR‐VFS on the mechanical properties, oil resistance, thermal stability, and low‐temperature performance were studied in detail. It was found that MR‐VFS could increase the tearing strength and high‐temperature thermal stability of fluorosilicone rubber. When the MR‐VFS weight content reached to 2 wt %, the tearing strength of MR‐FSR increased by 20.1% compared with that of common fluorosilicone rubber. However, MR‐FSR showed a similar low‐temperature resistance and a little worse oil resistance. The morphological study showed that incorporation of maleated rosin could intensify the microphase separation of fluorosilicone rubber. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.
