醛基官能聚醚多元醇及其制备方法和应用
摘要：
本申请公开了一种醛基官能聚醚多元醇，其化学式为：其中，A11选自C1～C3亚烷基中的一种；R11，R12，R13，R14独立地选自氢、烷基中的一种；n为正整数，满足2≤n≤100。本发明中的醛基官能聚醚多元醇具有350～20000Da的数均分子量，该醛基官能聚醚多元醇反应活性高，可用于聚氨酯合成领域。
摘要（英）：

The invention discloses formyl functional polyether polyol. A chemical formula of the formyl functional polyether polyol is shown in the description, wherein A11 is one of C1-C3 alkylenes, R11, R12, R13 and R14 are independently one of hydrogen and alkyl groups, and n is a positive integer and is greater than or equal to 1 but is smaller than or equal to 100. The formyl functional polyether polyolhas the number-average molecular weight of 350-20000 Da, is high in reaction activity and can be used in the field of polyurethane synthesis.
