Abstract
An anisotropy-free laminate having much higher strength and stiffness as compared with conventional articles is here disclosed which can be prepared by laminating an orientated ultra-high-molecular-weight polyethylene onto an adhesive layer obtained by modifying an olefin polymer with an unsaturated carboxylic acid and/or its derivative at a temperature lower than the melting point of the orientated ultra-high-molecular-weight polyethylene. The anisotropy-free material having high strength and high stiffness of the present invention can be substituted for various materials such as metals, lumber and FRP, and is also lightweight and excellent in water resistance.
