It has been established that chemical grafting via formation of oxazolidinone fragments bonding the POSS nanoparticles to polycyanurate network provides effective dispersing of the nanofiller inside polymer matrix. Using DMTA method it has been found that phase structure of the nanocomposites obtained is characterized by existence of two glass transition temperatures corresponding to Tg of the polycyanurate network and to the Tg of the hybrid structure; introduction of the nanofiller leads to shifting Tg to higher temperatures and appearance of the complex relaxation transition in the region 360-440 оС due to "constrained dynamics" effect.
