This area of training is relevant today, because the polymer products widely penetrate into our lives. there is a growing interest in the study of new technologies for the processing of polymers, as well as polymers - materials that can be reused, which is important for the environment. in russia and abroad continue to develop new technologies and materials. for example, in the united states, a group of scientists at the massachusetts technical university has developed an isotropic heat-conducting polymer that conducts heat in all directions. russian scientists have developed a new technology for creating 3d objects from fluoropolymers with nanoparticles. the development of science in the field of half-measures began with the discoveries of scientists carl ziegler and giulio natta, who were awarded the nobel prize.
