  • Polyolefins having improved dimensional stability in three-dimensional printing, articles formed therefrom, and methods thereof
    Patent number: 11912851
    Abstract: A compounded polymer composition suitable for manufacturing of isotropic three-dimensional printed articles may include an impact copolymer, a low crystalline ethylene/?-olefin copolymer; a nucleating agent; and filler, where the impact copolymer may include a matrix phase comprising a propylene-based polymer or copolymer; and a dispersed phase in the matrix phase, the dispersed phase comprising an ethylene-based copolymer, the ethylene-based copolymer having a C3-C12 comonomer, wherein the dispersed phase has a different composition than the matrix phase.
    Type: Grant
    Filed: May 14, 2021
    Date of Patent: February 27, 2024
    Assignee: Braskem America, Inc.
    Inventors: Juliana Breda Soares, Michelle K. Sing, Jacob Fallon, Alexandre di Pintor da Luz, Leonardo Ito, Hadi Mohammadi
  • Polyolefins having improved dimensional stability in three-dimensional printing, articles formed therefrom, and methods thereof
    Patent number: 11680158
    Abstract: A polymer composition suitable for manufacturing of isotropic three-dimensional printed articles, the composition including: a matrix phase including a propylene-based polymer or copolymer; and a dispersed phase in the matrix phase, the dispersed phase including an ethylene-based copolymer having a C3-C12 comonomer, wherein the dispersed phase has a different composition than the matrix phase, wherein the matrix phase has a crystallization half-time of less than 60 minutes.
