ABSTRACT:
A composition for bonding metal powders which is used in an amount of at most about 7 parts by weight as the solids content per 100 parts by weight of a metal powder for obtaining a flexible metal powder molding which is capable of tolerating deformation at a radius of curvature of up to 15 mm, the composition comprising as a main monomer an acrylic polymer having a weight average molecular weight of about 50,000 to 1,500,000 which comprises alkyl (meth)acrylate having an average carbon atom number of 3 to 12 in the alkyl moiety, or a mixture of the acrylic polymer and a resin which gives adhesive property, as a main component, the main component having a glass transition temperature in a range of about -70.degree. to -10.degree. C. and an elastic modulus in a range of about 0.05 to 50 kg/cm.sup.2 at 25.degree. C.
