The behaviour of information flows in different subfields of muticomponent polymer systems was compared for the years 1979 and 1983. The classification used enabled the maximum information on the species of polymer compositions to concisely be recorded. It was established that the information flows in the subfields of multicomponent polymer systems obeyed the law of literature scatter. In 1979 and 1983 about half of the total number of papers dealt with two species of polymer compositions: homopolymer blends and filled homopolymers. About 40% of species described in publications of 1979 did not appear either in journals or in proceedings of 1983. But new species accounted for 60% of the information flow in 1983.
