  • Plasticized polymeric compositions
    Patent number: 9359486
    Abstract: The present invention provides plasticized polymer compositions comprising an 7V-allcyl-2-pyrrolidone and a fatty acid ester. These compositions exhibit enhanced hardness, tensile strength, and/or elongation at break without the use of phthalate-based plasticizers. The plasticized polymeric compositions can be employed in a wide variety of applications, such as in sheeting, tubing, and coatings.
    Type: Grant
    Filed: October 4, 2010
    Date of Patent: June 7, 2016
    Assignee: ISP INVESTMENTS INC.
    Inventor: Hasan Kaytan
  • Plasticized PVC compositions with long term high temperature stability
    Patent number: 9145487
    Abstract: A stable, plasticized composition of PVC polymer including a C4-C30 alkyl pyrrolidone to plasticize said PVC into a flexible state and an organic phosphite ester stabilizer to impart long term high temperature stability.
    Type: Grant
