MIXTURE OF VINYLIDENHLORIDE INTERPOLIMER AND POLY(BUTYLENESUCCINATE) Russian patent published in 2017 - IPC C08L27/08 C08J5/18 

FIELD: chemistry.

SUBSTANCE: invention relates to a mixture for forming cast, blow-moulded extruded, cast, injection moulded or calendered products comprising, based on the weight of the mixture: A) from 80 to 98 wt % of a vinylidenechloride (VDC) interpolymer, wherein VDC interpolymer Includes units derived from one or more monomers of alkylacrylate, alkylmethacrylate or acrylonitrile, and B) from 2 to less than 15 wt % of poly(butylenesuccinate) (PBS), wherein BPS has M_w from 40,000 to 1,000,000 Dalton.

EFFECT: barrier films made from a composition containing a vinylidenchloride interpolymer and polybutylenesuccinate exhibit improved tensile strength, both in the longitudinal direction and in the transverse direction, without significantly reducing the rate of oxygen penetration, as compared to barrier films manufactured under similar conditions in all respects, except that the polybutylenesuccinate was replaced with an additional vinylidenchloride interpolymer.
