    摘要： A sheet of a polymer comprising at least 50 mol% of units of an olefin (e.g. polypropylene ) is coated on one surface with an aqueous solution or dispersion

    (A) 55 to 90% of a polymer comprising an olefin;
    (B) 1 to 30% of a copolymer of ethylene and acrylic acid; and
    (C) 10 to 30% of a polymer containing styrene units.

    The sheet optionally contains up to 65% of an inorganic fine powder.
    The adhesive layer adheres strongly to a cellular foamed polyurethane, to form a composite heat-insulating material without voids.
    The polymer sheet can be deep-drawn to shape, adhesive-coated, placed over the metal pressing of a refrigerator body or door, and the urethane components injected through a hole in the sheet so that the poly­urethane is formed between the sheet and the metal pressing and is foamed and adhered in situ ; the sheet can be a laminate having a lustrous outer surface layer.
