Uniaxial drawing of poly(4-methyl pentene-1) doped with modifying agents

Uniaxial drawing of poly(4-methyl pentene-1) in the rubbery state was studied. Both the pure polymer and that doped with organosilicon modifiers were examined. Optimal conditions for manufacture and orientational drawing of poly(4-methyl pentene-1) films were identified. Modification of poly(4-methyl pentene-1) with organosilicon compounds allows a higher degree of orientational drawing and makes it possible to perform the drawing under milder conditions, attaining greater effects than with a nonmodified polymer
