Effect of poly (acrylamide-co-acrylic acid salt) on anti-aging properties and adhesion between acrylonitrile butadiene rubber and polyester fabric

Abstract In this study, a multifunction polymeric adhesion promoter and anti-aging compound based on the triethanolamine salt of acrylamide acrylic acid copolymer (COS) was prepared characterized using Fourier-transform infrared spectroscopy (FTIR). The impact different COS contents tensile, adhesion, thermal properties NBR composite NBR/PET sandwich evaluated. composites containing displayed good retention their mechanical with increasing ageing time, while without showed decrease in its properties. highest tensile strength (17.5 MPa value 0.6%) after 7 days aging recorded for composite, which contains 5 phr (parts per hundred parts rubber) (COS 5), compared to 0), 15.1 -27.4%. addition, an improvement peel 16.4% 0. results thermogarvemetric analysis (TGA) supported anti-thermal effect COS, where initial decomposition temperature (Ti) increased by 11.7 9.3 °C, addition 10 respectively. other thermogravemetric parameters investigated significant increase values, confirms stability presence COS. Also, air permeability PET/NBR decreased 80% 7.5
