Abstract
Compositions based on propylene polymer, ethylene-vinyl acetate copolymer and organic peroxide, characterized in that they include, by weight: PA1 a) 10 to 49% of at least one propylene polymer; PA1 b) 90 to 51% of at least one ethylene-vinyl acetate copolymer in which the vinyl acetate content is from 12 to 40% by weight; PA1 c) between 50 and 1000 ppm (parts per million) of at least one organic peroxide. The sheets obtained by extrusion of these compositions can be employed for the internal trim in the motor vehicle industry.
