  • Patent number: 9988555
    Abstract: Polymers are disclosed that incorporate large portions of elastomeric polyamide oligomers connected with polyisocyanates. These polymers have enhanced properties over similar polyurethanes due to better hydrolysis resistance of polyamides over polyesters and better UV resistance of polyamides over polyethers. Polyurea linkages can also improve properties over polyurethane linkages. Composites and hybrids of these polymers and other polyamides with vinyl polymers are also disclosed and claimed.

  • Patent number: 9951212
    Abstract: Polyethylene is often stabilized with the combination of a primary antioxidant (such as a hindered phenol, a hydroxylamine or a lactone) and a secondary antioxidant (such as a phosphonite, a monophosphite, or a diphosphite). The diphosphite additives are not completely compatible with “linear” polyethylene. This results in “blooming” of the diphosphite to the surface of the finished polyethylene part or polyethylene film. The use of a preblend of ethylene vinyl alcohol (EVOH) and diphosphite mitigates this problem.
