Hyperbranched polyacetals (HBPAs) bearing cyclic carbonate (CC) terminals were synthesized from protocatechuric aldehydes bearing bifunctional trimethylolpropane (TMP) or glycerol (Gly) structures and then utilized to design polymer electrolytes and networked polymer materials. Since TMP‐based cyclic acetals (CAs) are thermodynamically more stable than Gly‐derived CSs, the copolymerization of these monomers favors to form HBPAs comprising TMP‐based acetal stems and Gly terminals. Consequently, HBPAs composed of larger amounts of TMP or Gly terminals were separately synthesized by changing monomer feed ratios. Their diol terminals react efficiently with diphenyl carbonate to give HBPAs bearing 5‐ or 6‐membered CC (5‐CC or 6‐CC) terminals. HBPAs bearing 5‐CC terminals were mixed homogeneously with lithium bis(trifluoromethanesulfonyl)imide to form uniform films showing lithium ion conductivity ranging from 8.2 × 10−9 to 2.1 × 10−3 S cm−1 at 23–80 °C, whereas networked polycarbonate and polyhydroxyurethane films were successfully fabricated using HBPAs having CC terminals. These results apparently indicate that HBPAs having CC terminals are useful scaffolds to design functional polymer materials. © 2019 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

含超支化聚缩醛的多功能环状碳酸酯:合成及其在聚合物电解质和网络化聚合物材料中的应用
由具有双官能三羟甲基丙烷(TMP)或甘油(Gly)结构的原儿茶酚醛合成带有环状碳酸酯(CC)末端的超支化聚缩醛(HBPA),然后将其用于设计聚合物电解质和网状聚合物材料。由于基于TMP的环缩醛(CA)在热力学上比源自Gly的CS更稳定,因此这些单体的共聚作用有助于形成包含基于TMP的乙缩醛茎和Gly末端的HBPA。因此,通过改变单体进料比分别合成了由大量TMP或Gly末端组成的HBPA。它们的二醇端基与碳酸二苯酯有效反应,生成带有5或6元CC(5-CC或6-CC)端基的HBPA。在23-80°C时-9至2.1×10 -3 S cm -1,而使用具有CC端的HBPA成功地制备了网状聚碳酸酯和聚羟基聚氨酯薄膜。这些结果显然表明具有CC末端的HBPA是用于设计功能聚合物材料的有用支架。分级为4 +©2019 Wiley Periodicals,Inc.J.Polym。科学,A部分:Polym。化学 2019,57,2295–2303
