ETHYLENE COPOLYMER HAVING IMPROVED IMPACT STRENGTH Russian patent published in 2012 - IPC C08F210/16 C08L23/08 C08J5/18 B29C49/00

Abstract RU 2469051 C1

FIELD: chemistry.

SUBSTANCE: copolymer of ethylene and a (C3-C18) α-olefin comonomer has density of 0.900-0.940 g/cm³, falling dart impact strength (F) satisfying the correlation with Vicat softening point as expressed by formulae (1) and (2), where V is Vicat softening point measured according to ASTM D 1525; and F is falling dart impact strength. The ethylene copolymer having improved impact properties is applicable to film, injection, compound, sheet, rotational, pipe or blow moulding.

EFFECT: producing ethylene copolymers having excellent processability and high impact strength owing to high rigidity.

13 cl, 4 dwg, 3 tbl, 14 ex
