Abstract
The present invention concerns a propylene polymer comprising at least two propylene polymer fractions of different melt flow index and a minor amount of at least one comonomer, said propylene polymer being further characterized by specific ranges for melt flow index, xylene solubles content and recovery compliance. Said propylene polymer is particularly suited for thermoforming. The present invention further concerns a process for producing said propylene polymer as well as its use in thermoforming.
