Abstract
Moulding compositions comprising a polyolefin, cellulose fibres and an unsaturated organosilane exhibiting a tensile elasticity modulus (E), measured at 100.degree. C., higher than 1250 MPa and a ratio G'/G" of their modulus G', representing their elastic response, to their loss modulus G", measured at 200.degree. C. and at a frequency of 0.1 rad/s (0.1 s.sup.-1), with a value of at least 0.80.
