Abstract : Are known two methods of orienting macromolecules, accomplished by stretching of the heated polymer above temperature of vitrification or the treatment of polymer by special catalysts or by modifiers. In the proposed method of obtaining polymeric materials the orientation of macromolecules is accomplished by the effect of electric or magnetic field, which makes it possible to improve the quality of the obtained polymeric materials and to decrease expenditures. Method consists of the following. Monomer or the mixture of monomers is poured into the reactor, manufactured from the nonmagnetic material and which has the form of cylinder. Reactor is placed into the electric or magnetic field, whose lines of force are directed in parallel to the axis of cylinder. Then they start polymerization. In the generating polymer the aggregates of molecules are oriented in parallel to the axis of cylinder.
