Synthesis and characterization of maleated rosin-modified fluorosilicone resin and its fluorosilicone rubber

Abstract:

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.
