Abstract
This invention relates to particular polyolefin compositions which contain, as stabilizers against UV-light radiations, open-chain amine compounds which are hindered in the alpha-position by alkyl radicals, said amine compounds corresponding to the following general formula: ##STR1## wherein R', R", R"', R.sup.IV, R.sup.V and R.sup.VI which can be equal or different, are radicals of aliphatic hydrocarbons with a number of C-atoms variable from 1 to 20, or can be hydrogen atoms, n is an integer variable from 2 to 12, and n' is an integer comprised between 1 and 15.
