    • The present invention relates to a thermoplastic composition which comprises at least one polyamide, which preferably has a melting point of less than 185°C, and at least one liquid polysiloxane compound which preferably has a viscosity of 750 to 100,000 mPas at 25°C and is OH terminated, wherein the thermoplastic composition is obtainable by a process comprising the steps: a) heating the at least one polyamide to a temperature above the melting point of the at least one polyamide and preferably below 185°C; 2a) adding under stirring the at least one liquid polysiloxane compound to the heated compound(s) of step 1a), wherein the temperature is kept above the melting point of the at least one polyamide and preferably below 185°C; and 3a) mixing the obtained mixture of step 2a) preferably at 80° to 180°C, more preferably 10 to 140°C. Use of this the thermoplastic composition according to the present invention in sealants, adhesives, or as rheological modifier or surface modifier. Furthermore, to a hot melt adhesive comprising the thermoplastic composition according to the present invention. And use of this hot melt in vehicle parts, constructions, windows, glazing, sanitary applications, fittings, roofing, plumbing, appliance application and bonding of panes.
    • 本发明涉及一种热塑性组合物,其包含至少一种优选具有小于185℃的熔点的聚酰胺和至少一种液体聚硅氧烷化合物,其优选在25℃下具有750至100,000mPa·s的粘度和 OH封端,其中所述热塑性组合物可通过包括以下步骤的方法获得:a)将所述至少一种聚酰胺加热到高于所述至少一种聚酰胺的熔点,优选低于185℃的温度; 2a)在搅拌下将至少一种液体聚硅氧烷化合物加入到步骤1a)的加热化合物中,其中温度保持在至少一种聚酰胺的熔点以上,优选低于185℃; 和3a)将所获得的步骤2a)的混合物优选在80℃至180℃,更优选10至140℃下混合。 在密封剂,粘合剂或流变改性剂或表面改性剂中使用本发明的热塑性组合物。 此外,涉及包含根据本发明的热塑性组合物的热熔性粘合剂。 并在车辆部件,结构,窗户,玻璃,卫生用品,配件,屋顶,管道,家电应用和窗格的粘合中使用这种热熔体。
