  • Publication number: 20090117358
    Abstract: Extruded polymer foams are prepared using brominated fatty acids, an ester, amide or ester-amide of a brominated fatty acid, a glyceride of one or more brominated fatty acids, or a polymerized brominated fatty acid as an FR additive. The brominated FR additives unexpectedly are stable at the extrusion temperatures, and provide excellent flame retardancy to the foams.

  • Publication number: 20030036619
    Abstract: The instant invention is a method for optimizing material transformation that includes the following six steps. The first step is to identify at least one physical variable that affects performance of a continuous unit operation for the material transformation. The second step is to select an initial set point of the at least one physical variable. The third step is to continuously perform the unit operation to produce a transformed material. The fourth step is to analyze the product to determine at least one component of interest of the transformed material. The fifth step is to select a subsequent set point of the at least one physical variable based on the analysis of the fourth step. The last step is to repeat steps three to five a sufficient number of times to optimize the unit operation.
