Diene rubbers such as natural rubber, SBR, and BR can be vulcanized by the action of phenolic compounds (van der Meer, 1943; Thelamon, 1963; Giller, 1966; Van Duin and Souphanthong, 1995), which are (usually di-)substituted by –CH 2

    This improved the strength of the rubber and limited the hardening and softening of the product with changes in temperatures. Sulfur alone was used as the vulcanizing agent up to the discovery of organic accelerators in the early part of the 20th century. It was quickly realized that the use of accelerators gave improved properties and

    RBOIERBO/conventional processing aids was then added followed by sulphur and accelerator. The total mixing time was kept at 16 minutes. In the case ofNBR-PVC blend the temperature of the rotor mixing head was kept at 150°C. NBR was first masticated for 2 minutes.

    The first weight loss stage ∼150–350 °C is due to the loss of a highly volatile matter, consists of the amount of oil added as a processing agent and a small amount ∼1–2% of decomposed fragments of the vulcanizing agent (sulfur or peroxide) vulcanization accelerator and antioxidant .
