  • Processes and compositions for injection blow molding
    Patent number: 9574064
    Abstract: The invention provides a process for injection blow molding an article, said process comprising injecting into a mold cavity a composition, comprising at least one ethylene-based polymer and less than, or equal to, 1000 ppm of a mold release agent, based on the total weight of the composition. The invention also provides a composition comprising a blend, wherein the blend comprises at least one high molecular weight (HMW) ethylene-based polymer, and at least one low molecular weight (LMW) ethylene-based polymer, and wherein the blend has an unsaturation level, as determined by IR, and expressed as vinyls per 1000 carbon atoms, less than, or equal to, 0.5 vinyls per 1000 carbon atoms, and wherein the high molecular weight (HMW) ethylene-based polymer has a density from 0.925 to 0.950 g/cc.
    Type: Grant

  • Polymer compositions comprising nucleating or clarifying agents and articles made using such compositions
    Patent number: 7786203
    Abstract: A polymer composition comprises a polyolefin and a nucleating or clarifying agent dispersed or dissolved in the polyolefin. Methods for producing the polymer composition and method for producing articles from the polymer composition are also described. Molded polymer articles and polymer film may be manufactured using the compositions of the invention.
