COPOLYMER OF ETHYLENE WITH PROPYLENE, ELASTOMERIC COPOLYMER, FORMED ARTICLE AND A METHOD OF COPOLYMER PRODUCING

摘要

FIELD: chemistry of polymers. SUBSTANCE: amorphous ethylene and propylene copolymers nonobligatory containing minimal amount of polyenes show the following properties: (A) mole percent content of propylene in copolymer (%P) and triads ratio EPE/(EPE + PPE + PPP) satisfies the following equation: 0.01%P + EPE/(EPE + PPE + PPP) ≥ 1; (B) less than 2% CH-groups in the chain are presented in alternatings (CH), where n - even number. These copolymers were synthesized in the presence of some metallocene catalysts containing two fluoroenyl groups connected together through the "bridge" group. EFFECT: improved method of synthesis.
