  • Irradiated polyolefin composition comprising a non-phenolic stabilizer
    Patent number: 8399536
    Abstract: The present subject matter relates generally to polymer compositions, and more particularly to irradiated polymer compositions comprising at least one non-phenolic stabilizer. The present polymer compositions comprise an unexpected balance of properties after being subjected to irradiation treatments, including an unexpected combination of a lower melt flow rate ratio (MFRr) and high melt tension after being irradiated, while minimizing negative yellowing effects.
    Type: Grant
    Filed: June 27, 2008
    Date of Patent: March 19, 2013
    Assignee: Basell Poliolefine Italia, s.r.l.
    Inventors: Jeffrey D. Abata, Ronald F. Becker, Vu A. Dang, Anthony J. De Nicola, Jr., Theodore Dziemianowicz
  • Process for producing high melt strength polypropylene
    Patent number: 7935740
    Abstract: The present subject matter relates to processes for irradiating visbroken propylene polymer compositions or extrudates of propylene polymer compositions containing a propylene polymer having a low polydispersity index and a non-phenolic stabilizer.
    Type: Grant
