Abstract
Polymer compositions are disclosed that contain a heterophasic polypropylene polymer. The polymer composition includes a first polymer phase that may comprise a polypropylene homopolymer and a second polymer phase that may comprise a rubber-like propylene-ethylene random copolymer. The polymer composition is made using Ziegler-Natta catalyst that results in a dramatically reduced VOC and oligomer content.
