  • Intelligent polymer compositions
    Patent number: 11046835
    Abstract: Polymeric compositions may include one or more adjunct polymers selected from a group of an ionomer and a polar polymer; and an intelligent additive, wherein when exposed to the external stimuli, the intelligent additive triggers a color change in the polymeric composition. Polymer compositions may include a nonpolar matrix polymer; one or more adjuncts selected from the group of an ionomer, a polar polymer, a metal salt, or combinations thereof. Polymer compositions may also include an intelligent additive, wherein when exposed to the external stimuli, the intelligent additive triggers a color change in the polymeric composition, wherein after at least 17 hours of exposure to the external stimuli, the polymer composition exhibits a ?E of at least 8 or more, maintaining the ?E of at least 8 or more for at least 5 days after the exposure to external stimulus is ceased.
    Type: Grant
    Filed: September 12, 2017
    Date of Patent: June 29, 2021
    Assignees: Braskem S.A., Universidade Federal do Rio Grande do Sul
    Inventors: Márcia Pires Fortes Ferreira, Leonardo Batista Ito, Luciane França De Oliveira, João Henrique Zimnoch dos Santos, Viviane Dalmoro
