More Information
Summary:A polymer composition with increased melt strength is disclosed. The polymer composition contains at least one polypropylene polymer combined with at least one melt strength modifier. The melt strength modifier can comprise a sorbitol derivative in an amount sufficient to change the melt strength characteristics and properties of the polymer. The polymer composition can be used in thermoforming processes and to produce polymer foams. The melt strength modifier can increase the melt strength of the polymer without having to induce branching in the polypropylene polymer.
