  • Publication number: 20030027975
    Abstract: Disclosed is a method for preparing saturated polyester used in various molded products, such as films, synthetic fibers, vessels and housings. In particular, the method improves mechanical properties, including tensile strength or impact resistance, of saturated polyester. In DMT method or TPA method, the saturated polyester is synthesized through transesterification or esterification and polycondensation, in which metal compounds, such as metal acetate compounds, metal hydroxides, and metal oxides, are added in the larger amounts upon synthesis, and thus crystalline internal grains are formed, thereby improving the mechanical properties. As such, the metal compound can be used alone or in combination with a phosphorous-based compound.

  • Patent number: 6476110
    Abstract: Rubber compositions filled with an unusually high content of solid magnetizable particles such as iron oxide or strontium ferrite but having great resistance to crack initiation and crack growth. This allows generation of strongly magnetized areas in rubber articles built with a rubber composition according this invention. This gives—also in those applications where a large distance between a row of magnetized areas and a sensor is necessary due to deformation—well-reproducible and well-recognizable signals despite existence of disturbing magnetic fields. The magnetizable particles are bonded to a rubber matrix by a bonding agent, namely an organo-functional silane.
