  • Publication number: 20180179309
    Abstract: Disclosed are methods for the production of polymers, including random copolymers (RCPs), in single reactor gas or slurry phase polymerization processes, and polymer compositions produced therefrom. The methods enable polymers having low melting temperatures to be made in gas and slurry phase polymerization processes, where they conventionally could not be made in these processes due to stickiness and fouling problems in the reactor.
