A molded catalyst has a catalyst material homogeneously distributed in an inorganic molding or a catalytic material anchored on the surface of molding is produced from a flowable molding composition made up of

High-temperature resistant molded catalysts and process for their

A profile strip, especially suitable for the production of window or door frames, has an optionally hollow core profile made from a glass fiber-reinforced PVC composition and a shell made from a synthetic resin compatible with PVC and exceeding the impact resistance of the core profile.

A glass fiber-reinforced polyvinyl chloride composition contains, per 100 parts by weight of polyvinyl chloride of a K value of between 55 and 75, 40-100 parts by weight of glass fibers having a diameter of between 5 and 25 .mu.m with a length of 0.5 to 12 mm, and 1-25 parts by weight of mineral filler having an average particle diameter of below 50 .mu.m.

A string for the stringing of rackets, bows, musical instruments and the like has a thread-like structure comprising at least one monofil of a synthetic resin mixture containing 99-86% by weight of polyvinylidene fluoride and 1-14% by weight of at least one polyacrylate. The monofil is melt-extruded and is stretch-oriented to impart improved elasticity thereto.

String of a vinylidene fluoride synthetic resin composition

A string for the stringing of rackets, bows, musical instruments and the like which has a thread-like structure of polyvinylidene fluoride. The string is obtained by extruding a rod of polyvinylidene fluoride at a melt temperature of the polyvinylidene fluoride, cooling the rod at a temperature between 60.degree.-150.degree. C., and then axially stretching the rod at this temperature following by cooling the rod to room temperature and thereafter cold-stretching the monofil. The string is characterized by an elasticity that approaches that of natural gut string.
