I. V.A. Kargin, the Soviet chemist, a member of the Academy of Sciences graduated from the University of Moscow in 1930, and headed the laboratory of colloid chemistry in the Karpov Institute. He founded the department of high polymers at the University of Moscow in 1956.

Kargin started his research with a study of colloid solutions, in which dispersed substances are not separate molecules but relatively large particles that are charged.

But the main trend in Kargin's research was the study of the structure of polymers and the relation between their structure and behaviour. He investigated deformation of amorphous polymers in a wide range of temperatures in terms of deformation of flexible molecules and their models in viscous media.

His research was the basis for the thermomechanical method of polymer characterization, the method widely used in the preliminary estimation of polymers.

II. The synthetic chemistry of polymers appeared in 1833, when Berzelius formulated the concept of polymerism.

Gay-Lussac synthesized the first polymer. During the subsequent years the field of macromolecular compounds has been enriched by a large number of new synthetic methods, the contribution of Russiun scientists to polymer chemistry being very substantial.

The works of Butlerov, Lebedev, Favorski, Shorygin, Kargin, Medvedev and others laid the foundations of polymer science. A great number of chemists are now engaged in synthesis of new polymers, 50% of all organic chemists working directly or indirectly on polymers, and a still greater number of scientists are occupied with use of the results of these investigations in industrial production, processing and application of polymers. It should be stated as an illustration that now in the course of one year, about 50,000 new polymers canbe synthesized, i. e. more than 160 new polymers per day or one new polymer every three minutes. Polymer technology of the present is based to a considerable extent on chemical moulding processes.
