POLYAMIDE RESIN COMPOSITION Russian patent published in 2015 - IPC C08L77/06 C08K5/98 C08K5/52 C08G69/28 C08K13/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a polyamide resin composition, which has excellent properties, such as thermal stability, resistance to chemical impact, strength, wear resistance and mouldability, and therefore is widely applied for the production of moulded products as an engineering plastics. The polyamide resin composition includes: a polyamide (A), containing a unit, representing diamine and containing not less than 70 mol% of a unit, representing p-xylylenediamine, and a unit, representing dicarboxylic acid and containing not less than 70 mol% of a unit, representing a linear aliphatic dicarboxylic acid, which has from 6 to 18 carbon atoms; and a filling agent (B). The polyamide (A) includes a polyamide with the concentration of phosphorus atoms, constituting from 50 to 1000 ppm, and a value YI, which by results of differential colorimetric analysis in accordance with JIS-K-7105, does not exceed 10. The content of the filling agent (B) constitutes from 1 to 200 wt.p. counted per 100 wt.p. of the polyamide (A).

EFFECT: invention makes it possible to obtain the resin with better mouldability and the moulded products based on the said polyamide resin with better thermal stability, low water absorption, and excellent sliding properties.
