  • Polymeric compositions for medical packaging and devices
    Patent number: 5849843
    Abstract: Multiple component polymer compositions for fabrication into articles. In particular, polymeric compositions comprising a heat resistant polymer; a radio frequency ("RF") susceptible polymer; a compatibilizing polymer; the composition having physical properties within the range a<40,000 psi; b>=70%; c<30%; d>1.0; e<0.1%; f<0.1%; g>=0.05; h<=60%; i=0; wherein: a is the mechanical modulus of the composition measured according to ASTM D-882; b is the percent recovery in length of the composition after an initial 20% deformation; c is the optical haze of the composition being 9 mils in thickness according to ASTM D-1003; d is the loss tangent of the composition at 1 Hz measured at melt processing temperatures; e is the elemental halogen content by weight of the composition; f is the low molecular weight water soluble fraction of the composition; g is the dielectric loss between 1 and 60 MHz and over temperatures of 25.degree. to 250.degree. C.
    Type: Grant
    Filed: November 16, 1993
    Date of Patent: December 15, 1998
    Assignee: Baxter International Inc.
