  • Patent number: 6083587
    Abstract: The present invention provides a multiple layer structure for fabricating medical products. The layer structure has a core layer of an ethylene vinyl alcohol copolymer having an ethylene content of about 25-45 mole percent, a solution contact layer of a polyolefin positioned on a first side of the core layer, an outer layer positioned on a second side of the core layer opposite the solution contact layer, the outer layer being selected from the group consisting of polyamides, polyesters and polyolefins; two tie layers--one of each adhered to the first and second sides of the core layer and positioned between the solution contact layer and the core layer and between the outer layer and the core layer, and wherein the structure is produced in a cast coextrusion process.

  • Patent number: 5998019
    Abstract: A multiple layer structure comprising a skin layer composed of a polypropylene copolymer with styrene ethylene-butene styrene block copolymer within a range of 0-20% by weight skin layer, and, a radio frequency ("RF") susceptible layer adhered to the skin layer. The RF layer has a first component of a propylene based polymer, a second component of a nonpropylene polyolefin, a third component of a radio frequency susceptible polymer, and a fourth component of a polymeric compatibilizing agent.

  • Patent number: 5993949
    Abstract: A multiple layer structure comprising a skin layer, a barrier layer, a radio frequency susceptible layer having a first polyolefin in an amount within a range of 30-60% by weight, a second polyolefin in an amount within the range of 25-50% by weight, a radio frequency susceptible polymer in an amount within the range of 3-40% by weight, a styrene and hydrocarbon block copolymer in an amount within the range of 5-40% by weight of the sealant layer.

  • Patent number: 5854347
    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.
