Claim Text:
1. A process for producing propylene-based in-reactor compositions comprising: (a) contacting propylene and from about 0 wt % to 10wt % C (b) contacting Component A, ethylene, and from about 3 wt % to 30 wt % of one or more C wherein the polymerizations are carried out in a reactor at a temperature of from about 50° C. to 140° C. where the reactor temperature is raised from the first to the second stage; wherein the metallocene catalyst system comprises: (c) obtaining a propylene-based in-reactor composition comprising Component A and Component B; wherein the propylene-based in-reactor composition comprises from about 60 wt % to 90 wt % of Component A, based on the weight of the in-reactor composition; and wherein the propylene-based in-reactor composition produced therefrom has a multimodal melting point with at least one melting point of 157° C. or greater.
