Unprecedented dependence of stiffness parameters and crystallinity on comonomer content in rapidly cooled propylene-co-1-pentene copolymers

A thorough evaluation of the mechanical behavior exhibited by fast crystallized propylene-1-pentene copolymers synthesized in a broad range of 1-pentene compositions is here described. Different mechanical magnitudes derived from loading, creep and unloading processes in depth sensing indentation me...
