FIELD: chemistry.
SUBSTANCE: addition of a stabilising amount of a mixture to high density polyethylene, where the said mixture contains 4,4'-bis(α,α-dimethylbenzyl)diphenylamine and sterically hindered phenol, enables to increase resistance to decomposition caused by chlorinated water.
EFFECT: pipes made from such a stabilising composition are suitable for conveying hot water, particularly chlorinated water.
