Carboxylated nitrile liquid rubber is a low molecular weight copolymer with butadiene and a.crylonitrile as the main chains and carboxyl groups at the end of the main chains. It has fluidity at room temperature.

The carboxyl groups at both ends of the main chain of CTBN molecules have high activity and can undergo chain extension or crosslinking reactions; The introduction of a.crylonitrile into the main chain of molecules has oil and high temperature resistance properties, which can promote the formation of polar compounds

The adhesion of the sexual interface can also improve the blending, oil resistance, and crack resistance properties with thermosetting structural resins.
