Abstract
Propylene and alpha olefin random copolymers are disclosed that have excellent flow characteristics. For instance, the copolymers can be formulated so as to have a melt flow rate of greater than about 45 g/10 min. While still retaining the above flow characteristics, the copolymer can also be formulated to have greater stiffness, low xylene soluble content, and excellent transparency characteristics especially when combined with one or more clarifying agents.
