    • PROBLEM TO BE SOLVED: To provide a melt-kneaded product of an incompatible polymer blend with a controlled co-continuous structural composition from an incompatible polymer blend, to provide a molded resin product of an incompatible polymer blend with a controlled co-continuous structural composition from the melt-kneaded product, and to provide a material obtained by subjecting the molded resin product to solvent treatment. SOLUTION: The melt-kneaded product is obtained in such a manner that a melt-kneaded resin or elastomer obtained by treating a filler, an incompatible resin or the like in specified ratios under the conditions where the speed of rotation of a screw is 600 rpm to 3,000 rpm and its shear rate is 900 to 4,500 sec -1 is sent from a rear end of the screw to its front end, then the melt-kneaded resin or elastomer is subjected to circulation where the melt-kneaded resin or elastomer is trapped in a space at the front screw, and then moved to the rear screw end, the co-continuous structure as the internal structure of the melt-kneaded product is controlled, and the size of the continuous phase is freely changed at mesoscopic level (0.3 to 100 μm). The molded resin product, and the material obtained by subjecting the molded resin product to solvent treatment are also provided. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供不相容的聚合物共混物的熔融捏合产物和来自不相容的聚合物共混物的受控共连续结构组合物,以提供不相容的聚合物共混物与受控共混物的模制树脂产物, 来自熔融捏合产物的连续结构组成,并提供通过使模塑树脂产物进行溶剂处理而获得的材料。 解决方案:熔融捏合产物是这样获得的,即在螺杆的旋转速度的条件下以特定比例处理填料,不相容树脂等获得的熔融捏合树脂或弹性体 600rpm至3,000rpm,剪切速度为900〜4,500sec。从螺杆的后端向其前端发送 -1 ,然后对熔融捏合的树脂或弹性体进行循环 其中熔融捏合的树脂或弹性体被捕获在前螺杆的空间中,然后移动到后螺杆端,作为熔融捏合产物的内部结构的共连续结构被控制, 连续相在介观水平(0.3〜100μm)内自由变化。 还提供了模塑树脂产品和通过使模制树脂产物进行溶剂处理获得的材料。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a thick object of isotactic polypropylene which is excellent in transparency and mechanical properties. SOLUTION: A transparent sheet of this invention is a polypropylene sheet formed by blending a crystal nucleator, and has an elastic modulus of 1.2 GPa or higher, a fracture strength of 90 MPa or higher, and a haze value of 11% or lower. A sheet is made by adding the crystal nucleator to polypropylene, extrusion-molding the crystal nucleator added polypropylene into a sheet, crystallizing the sheet on the surface of a chilled roll at a temperature of not lower than (Tm-90)°C and not higher than (Tm-40)°C, wherein Tm is the fusing point of the polypropylene and rolling the product under a specified condition at a temperature within the range of (αc-30)°C to (αc+20)°C, wherein αc is the crystal dispersion peak temperature of the loss factor at a frequency of 1 Hz in the dissonance forced oscillation dynamic viscoelasticity temperature curve. The sheet is not less than 1.2 GPa in elastic modulus and 90 MPa in maximum stress, and 11% or less in haze value. COPYRIGHT: (C)2006,JPO&NCIPI
