    Abstract: Fibres exhibiting good elastic properties and made from a thermoplastic, elastomeric polyolefin composition comprising (percent by weight): (A) 10 to less than 50% of one or more crystalline propylene polymers selected from homopolymers of propylene and random interpolymers of propylene and one or more recurring units in amounts up to 10%, the recurring units being selected from ethylene and a C 4 -C 10 α -olefin, the polymer(s) being insoluble in xylene at room temperature in an amount higher than 80%; and (B) over 50 to 90% of a polymer fraction comprising one or more interpolymers of ethylene and at least one α-olefin of formula H 2 C=CHR 2 , where R 2 is a C 1 -C 8 linear or branched alkyl, containing from 13 to less than 60% of recurring units deriving from ethylene. The fibres are prepared by a process operating at a value of output per hole ranging from 5 to 15 g/min, the pressure in the extruder ranging from 15 to 30 bar, the temperature in the extruder head ranging from 200 to 300° C.

    Abstract: A polyolefin composition comprising (parts by weight) (A) 100 parts of a crystalline isotactic propylene polymer resin having a molecular weight distribution (Mw/Mn) less than 3, the proportion of inversely inserted propylene units based on 2,1 insertions of a propylene monomer in all propylene insertions, i.e. 2,1 insertions, is as low as 0.5% or less, and a value of the melt flow rate (MFR) from 20 to 60 g/10 min; and (B) 0.1-1 part of a high molecular weight propylene polymer (B) having a value of melt strength from 5 to 4O cN. Fibres prepared from the said composition exhibit a good balance between elasticity and tenacity.
