摘要

利用非金属催化剂三乙基硼(TEB)/四丁基氯化铵(TBACl)催化环氧丙烷(PO)/二氧化碳(CO

)/苯酐(PA)/邻苯二甲醛(OPA)四元共聚，得到具有不同链段组成的高分子量的聚(缩醛-酯-碳酸酯) (PPCP-PAc). 随后在温和的酸性条件下选择性水解聚合物链中的缩醛键，得到了一系列分子量不同、聚酯(PE)含量不同的低分子量聚(酯-碳酸酯)二元醇(PPCP-DL). 通过基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)和

F核磁共振谱验证了PPCP-DL的两端均为羟基封端，且伯羟基含量为43%.

Abstract

In this study

a top-down strategy was adopted for the synthesis of poly(ester-carbonate) diols (PPCP-DL) by hydrolyzing high-molecular-weight poly(acetal-

-ester-

-carbonate) (PPCP-PAc). First

the nonmetal catalyst triethylborane (TEB)/tetrabutylammonium chloride (TBACl) was used to catalyze the quaternary copolymerization of propylene oxide (PO)

carbon dioxide (CO

)

phthalic anhydride (PA)

and

-phthalaldehyde (OPA)

affording high-molecular-weight PPCP-PAc with varied segmental compositions. Subsequently

the acetal linkages in the polymer backbone were selectively hydrolyzed under mild acidic conditions

yielding a series of low-molecular-weight PPCP-DLs with different molecular weights (1.6-3.3 kg/mol) and polyester (PE) contents (13 mol%-37 mol%). The end-group structures of PPCP-DL

confirmed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and

F nuclear magnetic resonance spectroscopy

revealed hydroxyl groups at both termini and a primary hydroxyl content of 43 wt%.
