Abstract

The invention relates to a metal polymer composite having properties that are enhanced or increased in the composite. Such properties include color, magnetism, thermal conductivity, electrical conductivity, density, improved malleability and ductility and thermoplastic or injection molding properties.

Claims

1-117. -117. (canceled)

118. A flexible automobile weight comprising:

(i) a shaped article comprising a metal and polymer viscoelastic composite; and

(ii) an attachment means;

wherein the viscoelastic composite has a tensile elongation of about at least 5%; and

comprises;

(a) a metal particulate, the particulate comprising a coating of a composite forming amount of an interfacial modifier capable of obtaining a viscoelastic composite with viscoelastic properties that permits flexible conformance to a curved wheel surface, the composite formed with other than a silane coupling agent that forms a chemical bond between the metal particle and the continuous polymer phase, the particulate having a particle size greater than about 10 microns, a particle size distribution such that there is an amount of particulate in the range of 10 to 250 microns; and

(b) a polymer phase.

119. The weight of claim 118 wherein the attachment means comprises an adhesive layer.

120. The weight of claim 118 wherein the attachment means comprises an adhesive strip.

123. The weight of claim 118 wherein the viscoelastic composite comprises a linear planar extrudate.

124. The weight of claim 118 wherein the weight has a viscoelastic character defined by the modulus and Poisson ratio of the composite that permits bending conformance to a curved wheel surface.

125. The weight of claim 118 wherein the viscoelastic composite has a tensile elongation of at least 100%.

126. The weight of claim 118 wherein the metal particle comprises an alloy particle.
