    摘要: 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.

    摘要: A high-strength and high-modulus polyolefin material can be continuously produced from a polyolefin in a powder form by feeding the polyolefin powder between a combination of endless belts disposed in an up-and-down opposing relation, compression-molding the polyolefin powder at a temperature lower than the melting point of the polyolefin powder by means of a pressing device while holding the polyolefin powder between the endless belts and conveying the same, and then rolling and stretching the resultant compression-molded polyolefin. The pressing device is constructed of pressing platens and corresponding sets of rollers, which are all accommodated within the respective endless belts. The rollers in each set are connected together, and the sets of rollers are arranged movably in an endless fashion between the respective platens and the endless belts associated therewith.

    摘要: According to the present invention, a polyolefin sheet, film or fiber having a high strength and a high modulus can be continuously produced by:feeding an ultra-high-molecular-weight polyolefin powder between a pair of upper and lower endless belts opposed to each other,conveying the polyolefin powder between the endless belts under compression to compression-mold the polyolefin powder at a temperature lower than the melting point of the polyolefin powder, the compression being continuously and smoothly effected, via the endless belts, by a pressing means comprising two sets of rollers which are arranged at the back sides of the endless belts so that each one roller of the two roller sets faces each other and each of which rollers is rotatably supported at the shaft ends by a frame, and thenrolling and stretching the resultant compression-molded polyolefin in this order.
