RESIN COMPOSITION, METHOD FOR PRODUCTION THEREOF AND MULTILAYERED STRUCTURE Russian patent published in 2016 - IPC C08L29/04 C08K3/24 C08K3/10 C08K5/92 B32B27/18 

FIELD: chemistry.

SUBSTANCE: invention relates to a resin composition, a method for production thereof and multilayer structures, including at least one layer of resin composition. Resin composition contains (A) an ethylene-vinyl alcohol copolymer, (B) at least one representative selected from a group consisting of carboxylic acid and carboxylate ion; and (C) a metal ion, where component (B) contains (B2) at least one representative selected from a set consisting of a compound having at least two carboxyl groups per molecule, and an anion of said compound. Molar ratio (B2/C) between compound having at least two carboxyl groups per molecule, or anion of compound (B2) and metal ion (C) ranges from 0.002 or more to 2 or less.

EFFECT: technical result is excellent characteristics of appearance and long-term processability during melt spinning, which enables inhibition of yellowing during melt spinning, in particular, even during melt spinning at high temperatures, not lower than, for example, 260 °C.
