  • Phosphite additives in polyolefins
    Patent number: 7179854
    Abstract: A polyolfin composition having high resistance to degradation is formed of at least one polyolefin component, bis(2,4dicumylphenyl)pentaerythritol diphosphite, triisopropanolamine, a hydrotalcite component, and at least one phenol component.
    Type: Grant
    Filed: December 15, 2003
    Date of Patent: February 20, 2007
    Assignee: Chevron Phillips Chemical Company LP
    Inventors: Mark K. Russell, David R. Battiste
  • Phosphite additives in polyolefins
    Patent number: 7135511
    Abstract: The whiteness and stability of a polyolefin have been found to be improved upon addition of a first phosphite, an arylalkyl diphosphite, and a second phosphite selected from a second arylalkyl disphosphite or a triarylphosphite. In addition, the addition of a triarylphosphite with an arylalkyl disphoshite has been found to improve the hygroscopic nature and the hydrolytic stability of the arylalkyl disphosphite.
    Type: Grant

  • Process for imparting improved whiteness to polyolefin resins
    Patent number: 6689829
    Abstract: Hydroxyalkylamines can, in addition to imparting antistatic properties, significantly improve the color, i.e., the whiteness, of polyolefin resins produced with chromium-based catalysts and metallocene catalysts. Additionally, such compounds can impart improved whiteness at a loading significantly lower than that required to impart antistatic properties. Surprisingly, the discovered improvement in whiteness is not, however, observed in resins produced using other types of catalysts.

  • Phosphite additives in polyolefins
    Patent number: 6680351
    Abstract: A polyolefin composition having high resistance to degradation, said composition formed by combining components comprising at least one polyolefin component produced from a transition metal halide catalyst, bis(2,4-dicumylphenyl)pentaerythritol diphosphite, triisopropanolamine, a hydrotalcite component, and at least one phenol component.

  • Phosphite additives in polyolefins
    Patent number: 6613823
    Abstract: The whiteness and stability of a polyolefin have been found to be improved upon addition of a first phosphite, an arylalkyl diphosphite, and a second phosphite selected from the group consisting of a second arylalkyl diphosphite and a triarylphosphite. In addition, the addition of a triarylphosphite with an arylalkyl diphosphite has as been found to improve the hygroscopic nature and the hydrolytic stability of the arylalkyl diphosphite.
