Title: Innovations by Anna Catherine Andrews
Introduction
Anna Catherine Andrews is a notable inventor based in Medina, OH (US). She has made significant contributions to the field of polyolefin compositions, holding a total of 4 patents. Her work focuses on enhancing the properties of materials to achieve both stiffness and toughness.
Latest Patents
One of her latest patents is titled "Impact Modified Polyolefin Compositions." This invention provides polyolefin compositions that exhibit both stiffness and toughness. The compositions include a polyolefin homopolymer resin, such as polypropylene, and an impact modifying fluid that contains a nonionic surfactant, with the option of including a diluent like mineral oil. The preferred nonionic surfactant is an ethoxylated sorbitan fatty acid ester, specifically ethoxylated sorbitan trioleate. The resulting unfilled impact modified polypropylene homopolymer demonstrates a Gardner impact strength of at least 100 in-lbs, a flexural modulus of at least 40 kpsi, and a tensile modulus of at least 60 kpsi.
Another significant patent is "Impact Modified Thermoplastic Olefin Compositions." This invention provides impact modified thermoplastic olefin (TPO) compositions that also exhibit both stiffness and toughness. The TPO compositions include a polyolefin homopolymer resin, such as polypropylene, along with a rubbery copolymer comprising at least one alpha olefin, and a nonionic surfactant that acts as an impact modifying fluid. The preferred nonionic surfactant for this invention is again an ethoxylated sorbitan fatty acid ester, specifically ethoxylated sorbitan trioleate.
