摘要: 通过合成双羟端聚(1,2-丙二醇己二酸酯)(PPA),经丁二酸酐酰化得双羧端PPA,再经(Bu4N)2CO3-THF铵化得铵化PPA,最后用铵化PPA与α,α-二甲基-β-丙内酯(PVL)嵌段共聚,首次合成了PPVL-PPA-PPVL的ABA型脂肪族聚酯嵌段共聚物。

Abstract: A new block copolymer of ABA type aliphatic polyester, polypiv-alolactone-poly (1 ,2-propandiol adipic acid ester) -polypivalolactone (PPVL-PPA-PPVL) was prepared through the synthesis of dihydroxy terminate PPA, dicarboxyl terminate PPA with succinic anhydride and then tetrabutyl ammonium salt of dicarboxyl terminate PPA by treating with (Bu4N)2CO3-THF and finally by the block copolymerization of tetrabutyl ammonium salt of dicarboxyl terminate PPA with PVL. The conversion of the block copolymerization of PVL was 93-96% and the efficiency of this polymerization was 95-96%,
