    摘要: The invention relates to storage-stable tris(hydroxyalkyl)isocyanurate polyol dispersions containing(a) from 2 to 70 parts by weight tris(hydroxyalkyl)isocyanurate,(b) from 98 to 30 parts by weight of at least one polyol having a functionality of from 2 to 8 and a hydroxyl number from 20 to 1800, and(c) from 0 to 20 parts by weight of one or more dispersion stabilizers.The dispersions are prepared by dissolving starting components A and B at temperatures in excess of 100.degree. C., in some cases adding a dispersion stabilizer and/or crystallization accelerator, with continuous and step-wise cooling of the mixture while stirring. The products are utilized for the preparation of polyurethane plastics, in particular polyisocyanurate foams containing polyurethane or polyurethane groups.

    摘要: A multi-speed hub for cantilever mounting to a bicycle frame generally includes a planetary gear mechanism, a hub shaft, a hub shell, a spoke shell, a driver and a driven gear. The hub shell is cantilever-mounted to the bicycle frame and configured to enclose the planetary gear mechanism and the hub shaft. The spoke shell, driver and driven gear are rotatably supported by the hub shell. One end of the hub shaft is indirectly supported by the hub shell and the other end of the hub shaft is fixed to the bicycle frame.
