Abstract: An improved foamable vinyl aromatic polymer composition and a process for preparing a vinyl aromatic polymer foam having incorporated therein a blend of alpha-olefin polymers are disclosed. The blend of alpha-olefin polymers may be virgin material or a portion of recycle feedstream, the recycle feedstream being prepared from adhesive film faced extruded vinyl aromatic foam laminate scrap. Foam materials having improved solvent resistance, ultraviolet light stability, and adhesive characteristics are prepared from the composition and process.

Abstract: A multilayer metal/organic polymer composite which has a formable thermoplastic polymer layer, a first metal layer adhered to the polymer layer and a second metal layer adhered to the first metal layer. The first metal layer is formed either from one metal or from an alloy of two or more metals. Suitable alloys are those which begin melting at a temperature within a range of from about 85 to 150 percent of the forming temperatures in degrees Kelvin of the polymer layer. If the first meal layer is formed from one metal, the metal is suitably, copper, silver, nickel or manganese. The second metal layer is a metal or an alloy of two or more metals that melts at a temperature which is less than that at which the first metal layer melts.
