Abstract
A significant part of the roofing sealing materials produced in the industry contains organic solvents. The use of such roofing materials causes significant harm to the environment and human health. In this study, new thermoplastic isoprene polymers with a softening point temperature in the range from 80 to 120°C have been synthesized, which make it possible to manufacture roll roofing materials used in practice without solvents. The process of production of polymers is based on the cationic polymerization of isoprene using catalytic system ethylaluminum sesquichloride-tert-butyl chloride. Varying the polymerization conditions allows one to control the molecular characteristics and softening point temperature of the polymers. A pilot batch of rolled roofing material was produced on the basis of the obtained polymer. As a result of the tests, it was shown that for a number of physical and mechanical parameters, the pilot batch of roofing material surpasses the known compositions using aliphatic hydrocarbon resins of the trade mark “Hikorez”.
