• NBR
• polysiloxanes
• tensile tests
• thermal stability

A series of elastomers, based on NBR, polysiloxanes (PS) were prepared and characterized by tensile tests, thermogravimetry (TG) and differential scanning calorimetry (DSC). Two kinds of vulcanizing agent, DMDBH (2, 5-dimethyl-2, 5-di(t-butyl perory) hexane) and DCP ( dicumylperoxide) were used to investigate the influence of different vulcanizing agents on properties of PSI NBR. The addition of PS to NBR was found to improve the thermal stability and decrease the tensile strength of NBR. The tensile strength decreased considerably while the elongation at break increased obviously with the increase of PS content. The series using DMDBH as vulcanizing agent showed a higher tensile strength and elongation at break than the series using DCP as vulcamzing agent. Simultaneity the thermal stability increased with the increase of PS content.
