A linear random N-substituted acrylamide copolymer comprising 65 to 99% by mole of ethylene units, 1 to 15% by mole of acrylate units and 1 to 35% by mole of acrylamide units, the copolymer having a weight average molecular weight of 1000 to 50000, and an aqueous composition, a resin film, a laminate, recording paper and a foamed article comprising the N-substituted acrylamide copolymer, respectively. The N-substituted acrylamide copolymer is excellent in antistatic ability for thermoplastic resins and does not lower physical properties such as transparency and elongation of films and articles which are formed from a thermoplastic resin. Moreover, the N-substituted acrylamide copolymer is excellent in anti-blocking ability so that the copolymer can be suitably used for various uses.

A molded laminated article is made from (a) a composite comprising a crosslinked polyolefin resin foam having an average gel proportion of 10 to 75% and an average expansion ratio of 5 to 40, in which the average expansion ratio in a portion having a thickness of 0.5 mm on the side of one surface of the foam is larger than the average expansion ratio in a portion having a thickness of 0.5 mm on the side of the other surface thereof and the difference between said average expansion ratios is from 2 to 20, and a skin material bonded to the surface having the larger average expansion ratio, and (b) a thermoplastic resin as a skeleton material, as follows. The composite is placed at a predetermined position intermediate between a pair of upper and lower mold halves so that the skin material side of the composite confronts or is in contact with the molding surface of one of the mold halves and the melt of the thermoplastic resin confronts or is in contact with the molding surface of the other of the mold halves; and the mold halves are clamped to effect compression molding. The molded laminated article is useful as an interior article for a vehicle.
