摘要：: <p>Crystalline polymers of olefins in the form of granules or nonextruded particles having regular geometric form, containing one of more of the following stabilizers: a) from 0.01 to 0.5% by weight of one or more organic phosphites and/or phosphonites; b) from 0.005 to 0.5% by weight of one or more HALS (Hindered Amine Light Stabilizer); and optionally one or more phenolic antioxidants in concentration not higher than 0.02% by weight. The fibers obtained from said polyolefins have high thermoweldability and good resistance to yellowing and aging.</p>
