Modem progressive polymers

Nowadays, the radioelectronics, electrotechnical. Avia, shipbuilding and fields of industry can not develop successively without using the modem progressive polymers such as polyarylates, polysulfones, polyesterketones and others which are perspective constmction materials. Only Russian industry involves 50 types of plastics including more than 850 labels and various modifications [14], As a result, the specific weight of products of engineering areas and several other branches of industry produced with help of plastics grew from 32-35% in 1960 till 85-90% in 1990.

Separation of gases and vapors by means of selective permeable membranes belongs to progressive modem technologies that successfully compete with gas separations by adsorption on porous solids. To compare the influence of different polymer fillers on the properties of heterogeneous membranes. 

For four decades from the 1920 s to the 1960 s, enormous progress was made in understanding the structure of native polymers and synthesizing artificial counterparts. Instead of giving a detailed chronological account of the events, I shall describe three representative meetings which took place during this period, because they have become classical milestones of modem chemical history. 

Composite polymeric materials with improved properties find wide applicability in modem technology. One of the most progressive trends of filled materials making, where the filler defines synthesis kinetics, stmcture and properties of final product and at the same time performs the role of catalyst, is polymer s synthesis in the presence of inorganic fillers [1, 2].
