IONISING RADIATION-RESISTANT POLYMER COMPOSITION Russian patent published in 2014 - IPC C08L23/16 C08J3/20 C08K5/13 C08K5/16 C08K5/49 

Abstract RU 2534900 C1

FIELD: chemistry.

SUBSTANCE: polymer composition contains a propylene and ethylene copolymer, a sterically hindered amine, a stabiliser and a Remafin dye concentrate. The sterically hindered amine is (N-beta-hydroxyethyl-2,2,6,6-tetramethyl-4-hydroxy-piperidyl succinate), and the stabiliser is di(4-methyl-2,6-ditertbutylphenyl)phosphorous acid, oligomeric diphenoxy-propylidene-phenyl ether of phenyl phosphonic acid and pentaerythryl-tetrakis-3-(3',5'-di-tert-butyl-4'-hydroxyphenyl)propionate.

EFFECT: disclosed composition enables to obtain nonwoven material with high elasticity, which is retained before and after exposure to ionising radiation.
