The present disclosure is directed to random propylene/α-olefin compositions, articles, and processes for producing the same. The present compositions contain a random copolymer of propylene and α-olefin. Polymerization with an improved catalyst composition increases the molecular weight distribution of the copolymer and increases the randomness of comonomer distribution to yield random propylene/α-olefin copolymers with improved stiffness and/or improved optical properties.
