Vulcanization temperature regulation

Another way of reducing the temperature of vulcanization of rubber binder is regulation of the micro structure and viscosity of the dienic oligomer. We know that liquid dienic rubbers are the macromolecules of oligomers withl,4-cis-, 1,4-trans-, and 1,2-vinyl- links with viscosities from 0.4 up to 10 Pac. It was found experimentally that production of cold-cured RubCon is possible if the content of 1,4-cis- links in a macromolecule of rubber is more than 65%, and the viscosity of the polymer is more than 17 Pa c. Increasing the viscosity of rubber up to 7 Pa c leads to lowering of the structurization temperature from 125°C to 60°C.
