Abstract

The high-dispersed inorganic phase can be obtained in the polymer matrix. In according with such idea we use epoxy, cyclocarbonate and methacrylic oligomers for creation of nano-structured organic-inorganic hybrids. To obtain this several families of curing agents aryl- and alkyl-silanes dendro-aminosilane hardeners were synthesized on the base of aminosilanes and tetraethylortosilicate (TEOS)or tetraethyortotitanate (TEOT). Using as interpenetrating polymer networks (IPN) principle in production of composite materials provides a unique possibility to regulate their both micro-and nano-structured properties. Coatings have improved wear resistance and photo-stability. The key advantage of the technology is based on the development of a class of additives, which is adaptable to all kinds of coatings. Main advantages were received for hybrid nonisocyanate polyurethanes.
