COMPOSITION CONSISTING OF POLYAROMATIC POLYAMIDE AND CROSS-LINKED POLYOLEFIN Russian patent published in 2016 - IPC C08L77/06 C08L23/08 C08L33/06 B32B27/34 B32B27/30 

Abstract RU 2583455 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a composition for making articles. Composition contains at least one polyaromatic polyamide and at least one cross-linked polyolefin. Cross-linked polyolefin is obtained from at least one product (A) containing unsaturated epoxide, and at least one product (B) containing unsaturated carboxylic acid anhydride. According to invention, weight content of (A) and (B), designated respectively as [A] and [B], are such that ratio [B]/[A] varies from 3 to 14, preferably from 4 to 9. Invention also describes a method of producing a composition and use thereof for making a single-layer or multilayer structure.

EFFECT: technical result is smooth and glossy surface products, in particular, pipes, with very small amount or even complete absence of "adapter saliva".
