  • Dispersions of high carboxyl polyamides into polyesters
    Patent number: 9018293
    Abstract: A polymer composition, stretched and unstretched articles and processes to make stretched and unstretched articles from that composition are set forth wherein the composition comprises a blend of a polyamide wherein the amino to carboxyl end group ratio of the polyamide polymer is less than 1.0 when the relative viscosity of the polyamide polymer is less than 2.0, and less than 0.30 when the relative viscosity is in the range of 2.0 to 2.3 and less than 0.20 when the relative viscosity is greater than 2.3, a crystallizable polyester and an interfacial tension reducing agent.
    Type: Grant
    Filed: October 16, 2012
    Date of Patent: April 28, 2015
    Assignee: M&G USA Corporation
    Inventors: Douglas David Callander, Gianluca Ferrari, Arianna Giovannini, Maria Teresa Scrivani, Simone Ferrero
