POLYAMIDE RESIN COMPOSITION Russian patent published in 2016 - IPC C08L77/06 B32B1/02 B32B27/34 B32B27/36 C08G69/28 C08J3/22 C08K5/09 

FIELD: chemistry.

SUBSTANCE: invention relates to a polyamide resin composition which contains a polyamide (X), which includes a diamine unit, including 70 mol% or more of a methaxylylene diamine unit, and a dicarboxylic acid unit, including 70 mol% or more of an adipic acid unit or a sebacic acid unit, and an alkaline compound (A), which is at least one compound selected from carbonates, bicarbonates or carboxylates of alkali or alkali-earth metals, where the following equations (1)-(3) are satisfied: 0.03≤P≤0.32 (1), 2.2≤M≤26.1 (2), 9.3<M/P≤186 (3), where P denotes the molar concentration, expressed in mcmol/g, of phosphorus per gram of the polyamide resin composition, M denotes the sum, expressed in mcmol/g, of the values obtained by multiplying the molar concentration of an alkali metal atom and the molar concentration of an alkali-earth metal atom per gram of the polyamide resin composition by the valence thereof, respectively. The invention also describes a method of producing the polyamide resin composition, a polyamide mother batch and a multilayer moulded article.

EFFECT: good colour hue of the polyamide resin composition, production of a smaller amount of gel and a burnt residue when making articles from the composition, such as films, sheets, fibres and multilayer articles.
