    摘要: A method of preparing a polystyrene blend that includes combining a first polystyrene composition having a first melt flow index with a second polystyrene composition having a second melt flow index and forming a polystyrene blend, the second melt flow index being at least 2 dg/min higher that the first melt flow index. The polystyrene blend has an observed tensile strength value greater than 3% above the expected tensile strength value. The second polystyrene composition can include a recycled polystyrene material, which can include expanded polystyrene. An alternate method of preparing the polystyrene blend includes combining a polystyrene composition with a styrene monomer to form a reaction mixture, polymerizing the reaction mixture and obtaining a polystyrene blend, where the polystyrene containing composition has a melt flow index at least 2 dg/min higher than the melt flow index of the styrene monomer after it has been polymerized.

    摘要: Cellular and multi-cellular polystyrene and polystyrenic foams and methods of forming such foams are disclosed. The foams include an expanded polystyrene formed from expansion of an expandable polystyrene including an adsorbent comprising alumina, wherein the multi-cellular polystyrene exhibits a multi-cellular size distribution. The process for forming a foamed article includes providing a formed styrenic polymer and contacting the formed styrenic polymer with a first blowing agent and an adsorbent comprising alumina to form extrusion polystyrene. The process further includes forming the extrusion styrenic polymer into an expanded styrenic polymer and forming the expanded styrenic polymer into a foamed article.
