  • Patent number: 11124618
    Abstract: Foamed reactor made thermoplastic polyolefins (rTPOs), and articles made therefrom, are described. The compositions have an rTPO combined with a foaming agent. The foaming agent can be a physical blowing agent and/or a chemical foaming agent, and may include optional nucleating agents. Some compositions utilize a masterbatch having one or more chemical foaming agents to foam the rTPOs. The rTPOs have a large melt flow rate range and flexural modulus range that translate into a broad scope of potential applications and foamed architecture. This allows the combination of rTPOs and foaming agents to be fine-tuned for selected foaming application.

  • Publication number: 20200263051
    Abstract: A method of preparing a biocompatible polymeric coating includes preparing an aqueous polymer solution by contacting and reacting methacrylic acid and at least one methacrylate or phosphorylcholine. The methacrylate or phosphorylcholine may include hydroxyethyl methacrylate, polyethylene glycol monomethacrylate, or methacryloyloxyethyl phosphorylcholine. An aqueous coupling agent solution is prepared and is either applied to the substrate surface or is mixed with the polymer solution to form a coating solution. If the coupling agent solution was first applied to the substrate surface, the polymer solution is then applied to the primed substrate surface. Alternatively if a coating solution was created, the coating solution is applied to the substrate surface. In either event, the polymer solution and coupling agent solution react with the substrate to form the biocompatible polymeric coating on the substrate surface.
