COPOLYMERS OF ETHYLENE WITH PROPYLENE, METHOD OF THEIR SYNTHESIS, FORMED ARTICLES

摘要

FIELD: copolymers. SUBSTANCE: new copolymers of ethylene with propylene and nonobligatory minimal ratios of diene or polyene showing high elastomeric properties at nonhardening state. Copolymers show structure where propylene is presented partially in the form of short isotactic alternatings. The value of residual elongation (200%) less 15% is occurred when the ratio ethylene:propylene has the required values, and an intrinsic viscosity value is above 3. EFFECT: enhanced quality of copolymers.
