    摘要： The subject of the present invention is a process for the preparation of new high-molecular weight polyester-polycarbonates which contain incorporated segments containing carboxyl groups and can be processed by thermoplastic methods, which process is characterized in that segments which contain carboxyl groups and have average molecular weights Mn (number-average of the molecular weight determined via the acid number of the segments containing carboxyl groups) of greater than about 600, preferably of greater than about 800 and in particular of between about 1,000 and 20,000, are reacted with diphenols and phosgene by the known two-phase boundary polycondensation process at a pH value of between about 9 and 14 and at a temperature of between about 0.degree. C. and 80.degree. C. and preferably of between about 15.degree. C. and 40.degree. C. and the resulting reaction products are either subjected to a heat treatment at temperatures of between about 40.degree. C. and 170.degree. C. for between about 5 minutes to 24 hours or are subjected, at temperatures of between about 130.degree. C., and 250.degree. C., to shear forces of between about 720 and 2520 kJ/kg of polymer or are gelled in solution by organic solvents. The invention also relates to the polyester-polycarbonates which are obtainable according to the invention and contain at least 2 phases, resulting from the polycarbonate constituent and the segment fraction which has terminal carboxyl groups.

    摘要： A freewheel hub for bicycles to provide propulsion by means of a plurality of sprockets when a derailleur is used. A sprocket or gear carrier transmits the rotational forces introduced to the sprockets mounted on the sprocket carrier by means of a drive sleeve, a ratchet and a pawl carrier to a hub sleeve in the direction of rotation of the drive, whereby the ratchet represents a freewheel in the opposite direction of rotation. The propulsion unit, which consists of the sprocket carrier and the drive sleeve, is divided into two parts, and can therefore be manufactured easily with regard to its driving gearings and pawl gearing.

    摘要： The present invention is directed to a process for the production of polyisocyanate mixtures containing isocyanurate groups and uretdione groups in a molar ratio of about 1:9 to 9:1 by oligomerizing a portion of the isocyanate groups of hexamethylene diisocyanate using trialkyl phosphines and/or peralkylated phosphorus acid triamides as the catalysts which accelerate the dimerization and trimerization of isocyanate groups, terminating the reaction at the desired degree of oligomerization by the addition of a catalyst poison and removing unreacted hexamethylene diisocyanate to a residual content of at most 0.5% by weight, characterized in that, before addition of the catalyst, the hexamethylene diisocyanate starting material is freed from carbon dioxide to a residual content of less than 20 ppm (weight).The present invention is also directed to the polyisocyanates containing uretdione groups and isocyanurate groups obtainable by this process and their use, optionally blocked by blocking agents for isocyanate groups, as the isocyanate component for the production of polyisocyanate polyaddition products.
