    摘要： A method for producing foamed thermoplastic resin profiles with an outer skin layer of increased hardness and an inner foam structure which may be used in place of wooden articles. The outer skin has a smooth surface and a good appearance, and the inner portion enclosed by the skin has a uniform foam structure. Also, with this method an improved foaming efficiency can be obtained. The method comprises a step of melting and kneading a mixture consisting of a thermoplastic resin and a foaming agent without causing the gasification of the foaming agent, a step of heating the melted and kneaded mixture obtained in the previous step to cause the gasification of the foaming agent without agitating the mixture and under a pressure sufficient to supress the substantial foaming of the mixture, thereby forming an expandable melted resin mixture containing microbubbles which are prevented from gathering and uniting, and a third step of causing the melted resin obtained in the previous step to expand while cooling the resin by leading the resin to a foaming die under low temperature and low pressure conditions.

    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.
