A polymer of a mono-olefinic hydrocarbon is admixed with a copolymer of ethylene and an ester of formula CHR1=CR2.COOR3 where R1 is -H or -COOR4, R2 is -H or -CH3 and R3 and R4 are a C1- 5 alky radical, the copolymer being treated, before or after its incorporation into the polyolefine with an amino-alcohol of formula <FORM:1106403/C3/1> where R5 and R6 are -H or a hydrocarbon radica whose hydrogen atoms may be substituted with amino or alkyl-substituted amino radicals, and R7 is a divalent aliphatic, alicyclic or aromatic hydrocarbon radical; or with an alcohol of formula X-R8-OH, where R8 is a divalent aliphatic hydrocarbon radical and X is a nitrogen containing heterocyclic radical which is in the o -position with respect to the hydroxyl group. The polyolefine may be polypropylene. The copolymer may be derived from ethylene and methyl or ethyl acrylate or methacrylate. The alcohol may be b -(N,N-diethylamino) ethanol, g -(N,N-dibutylamino) propanol, b -(1-piperidino) ethanol, a morpholino-ethanol, b - (1 - pyrrolidino) ethanol, (2-pyridino) methanol or b -(N,N-dimethylamino) ethanol. The polyolefine composition may be formed into a fibre by extrusion into a filament which is then stretched.
