The electroconductive layer further has a pore, and an inner wall of the pore is constituted by a part of the matrix and a part of the domains. The domains constituting the inner wall protrude into the pore at sites on the inner wall.

The present invention provides a highly dispersible metallic acrylate composition containing specific content of a graphene, a flake graphite or a combination thereof as a thermally conductive powder, and thus has better stability and dispersivity, which leads to advantages of low adhesion to the metal surface and ease of mixing in resin. Moreover, the metallic acrylate composition can be applied to resin composition as an auxiliary crosslinking coagent for enhancing mechanical strength and good uniformity of cell dispersion in the foamed product, such that the foamed products can be used as architectural materials, materials of daily commodities, vehicle materials, damping and cushioning materials, packing materials, sport pad materials, or shoe materials.
