Abstract

Propylene polymer including at least two propylene polymer fractions of different melt flow index and a minor amount of at least one comonomer may be characterized by specific ranges for melt flow index, xylene solubles content and recovery compliance. The propylene polymer may be particularly suited for thermoforming.
