Abstract
The study in order to obtain high adhesion and high-elastic coating adhesive and sealant compositions. Received, they polyoxydepropylenglycol and 4.4¢-diphenylmethaneduso-thionats, kinetics of sopolicondensation. It has been established that the reaction of education migration flows tint urethane polymerization based on accession to the nitrogen Atom mobile hydrogen atoms polyester. By IR spectroscopy, we investigated the morphology of synthesized sooligomers. It is shown that combining the sooligomer with butyl rubber (copolymer of isobutylene and isoprene) increases the elasticity of the system, removes shrinkage and improves thermal and chemical resistance. For the purpose of obtaining highly adhesive and highly elastic composite material made of polyurethane sooligomers mixtures has been studied with butyl rubber (BC) with high rates of heat resistance, flexibility, chemical resistance to aggressivesurroundings, resistance and water resistance. It is shown that when mixing polyurethane copolymer with butyl rubber polymer formation occurs the system, macromolecules which mechanically interacting among themselves form a so-called grid interpenetrating. This composition is also the most resistant to an aggressive surroundings, which makes its application promising. Comparison of differential thermal analysis sooligomers and compositions sooligomer+butyl rubber, shows that the composition of thermally more stable than sooligomer. In the work solved an important scientific and technical challenge of improving the quality of adhesive compositions. The study developed recommendations for improving the properties of adhesive compositions, competitive with respect to existing analogues for recipe structure, technology access and use adhesive compositions. Received by the specified by compositions can be used in the manufacture of polymer products for the oil, engineering industries.
