采用双辊磨粉机对天然橡胶与邻氨基苯酚进行接枝共聚。用红外光谱和核磁共振氢谱对所制备的接枝抗氧剂NR-graft-o-AP进行了分析。评价了含市售防老剂PBN、接枝防老剂NR-graft-o-AP和对照硫化胶的热稳定性、力学性能和超声衰减系数。热稳定性研究结果表明，NR接枝邻AP对NBR硫化胶的热处理保护效果明显优于市售防老剂PBN和对照混炼胶。所制备的接枝防老剂提高了NBR硫化胶的力学性能。© 2010 Wiley Periodicals，Inc.应用聚合物科学杂志，2011年
The grafting copolymerization of natural rubber and o-aminophenol was carried out by using two-roll mill machine. The prepared grafted antioxidant, NR-graft-o-AP, analyzed by using Infrared and 1H-NMR Spectroscopy techniques. The thermal stability, mechanical properties, and ultrasonic attenuation coefficient were evaluated for NBR vulcanizates containing the commercial antioxidant, PBN, and the prepared grafted antioxidant, NR-graft-o-AP, and the control vulcanizate. Results of the thermal stability indicate that the prepared NR-graft-o-AP can protect NBR vulcanizate against thermal treatment much better than the commercial antioxidant, PBN, and control mix, respectively. The prepared grafted antioxidant improves the mechanical properties of NBR vulcanizate. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
