Abstract RU 2824600 C2

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a polyolefin resin crystallisation nucleating agent, a polyolefin resin nucleating agent composition which contains a crystallisation nucleating agent, a polyolefin resin masterbatch, and a polyolefin resin composition, as well as a molded article from the composition, a film from the composition, a method of producing a porous film and packaging. Polyolefin resin crystallisation nucleating agent includes a compound represented by following formula (1):

where M is an atom of a monovalent - trivalent metal having a specific gravity of 4.0 or less, or an atom of a divalent or trivalent metal, bonded with a hydroxyl group, having specific gravity of 4.0 or less, selected from a group comprising: sodium, calcium or hydroxyaluminium; is 1 or 2; b is 1; x is integer 1 or 2; ax = 2b is performed; and Z is any of the following groups:

EFFECT: providing a nucleating agent for crystallisation of a polyolefin resin, which has a suitable formation effect β-crystals.
