本发明的实施方式涉及甲硅烷基改性的聚合物和生产其的方法。
发明背景
含可交联甲硅烷基的聚氧化烯聚合物作为原料聚合物广泛用于建筑或工业用途的密封材料、粘合剂、涂布材料等。该含可交联甲硅烷基聚合物可以根据以下多种方法生产,例如经由Williamson醚合成的乙烯基封端聚醚的氢化硅烷化,由异氰酸酯封端的预聚物聚醚的氨基硅烷反应,或由羟基封端的预聚物聚醚的异氰酸基硅烷反应。然而,一些方法(特别是由异氰酸酯封端的预聚物聚醚的氨基硅烷反应和由羟基封端的预聚物聚醚的异氰酸基硅烷反应)可以导致产物具有高的粘度,在产物配制期间需要大量的稀释溶剂。此外,Williamson醚合成可产生作为副产物的盐,由于可能需要除去该盐,因此增加处理步骤。
因此,需要使用非典型(non-typical)聚醚多元醇制备含可交联甲硅烷基的聚合物。
发明概述
本发明的实施方式提供了使用非典型聚醚多元醇制备的可交联甲硅烷基聚合物。
在一种实施方式中,存在一种包含可交联硅烷封端的聚合物的组合物,该聚合物在每个分子中具有至少一个可交联甲硅烷基。该可交联硅烷封端聚合物包含至少一种标称官能度至少为2的多元醇和异氰酸酯封端的氢化硅烷化聚合物的反应产物,其中该多元醇为聚碳酸酯多元醇、基于天然油的多元醇、聚氧亚烷基胺、双官能芳香族胺、聚丁基氧化物聚醚多元醇和聚丁二醇中的至少一种。该异氰酸酯封端的氢化硅烷化聚合物包含至少一种异氰酸酯和氢化硅烷化聚合物在约100至约250的异氰酸酯指数下反应的反应产物。该氢化硅烷化聚合物包含氢化硅烷化效率(由1H-NMR测定)为至少约70%的氢化硅烷化反应的反应产物,并且该聚合物包含以下至少一种a)和b)的反应,a)在每个分子上具有至少一个不饱和基和至少一个醇羟基的聚合物,其数均分子量在约100至约5000之间,b)在每个分子上具有氢硅键和可交联甲硅烷基的化合物。
