Abstrakt:	ABSTRACT Hindered phenol exterminated hyperbranched polyester (mHBP) is fabricated by esterification reaction. The mHBP is introduced into nitrile rubber (NBR) to prepare NBR/mHBP blends. Structure, damping and mechanical properties of NBR/mHBP blends are investigated by Fourier transform infrared spectroscopy (FTIR), 1H-NMR, dynamic mechanical thermal analyzer (DMTA), and tensile tester. FTIR spectra of the blends illustrate the intermolecular hydrogen bonding between the NBR and mHBP, contributing to the improvement of damping and mechanical properties. The results indicate that, with the increasing mHBP content, the Tg of the blends shifted to a higher temperature with a broadening temperature range and improved mechanical properties, showing an application in adjusting the Tg and temperature range without decreasing of loss factor. © 2015 Wiley Periodicals, Inc.
