Ph of butadiene
WebAcrylonitrile butadiene rubber /EPDM blends (at 70/30 or 80/20 ratio) have a better ozone resistance than NBR alone. The heat resistance of NBR can further be enhanced by the use of low sulfur or sulfur donor curing systems. Plasticizers of low volatility should be chosen to produce heat stable compounds. Webbutadiene block copolymer. All three monomers react through the macroradical interacting with the double bond of butadiene. The site of reaction has been established by infrared spectroscopy. For methyl acrylate every unit of the styrene –butadiene block copolymer is grafted but only a small fraction is grafted when the acids are used.
