This invention provides a thermoplastic polymer foam having a density of up to 800 kg/m,. The foam is made from a hydrogenated vinyl aromatic polymer that contains pendant cycloaliphatic groups. This polymer is conveniently made by hydrogenating a poly(vinyl aromatic) polymer such as polystyrene or a polystyrene-butadiene block copolymer. A suitable blowing agent is a mixture comprising (a) one or more fluorine-containing carbon compounds and (b) carbon dioxide, nitrogen, an alcohol having from 1 to 4 carbon atoms, a linear or cyclic hydrocarbon having from 1 to 6 carbon atoms, a ketone, an alkyl ether, an alkyl halide, water or a mixture thereof.

Hydrogenated vinyl aromatic polymer foams

A water wettable corrosion resistant plastic clad metal laminate suitable for forming into heat transfer partitions for use in apparatus for simultaneous heat and mass transfer.

Plastic clad metal laminate for heat transfer partitions

A polymeric blend comprising a polypropylene resin and very low density polyethylene are particularly suited for preparation of films which are readily adhered to metal surfaces. Sheet metal laminates according to the foregoing design are usefully employed in the manufacture of components for aerosol containers.

Polymeric blend and laminated structures prepared therefrom

A multi-layered adhesive composition particularly suited for adhesion between metallic substrates and vinyl chloride polymer resins particularly highly plasticized vinyl chloride polymer resins comprising a metal adherent layer, an intermediate layer and a vinyl chloride polymer adherent layer.
