AlEt3-H2O-H3PO4 catalyzed polymerizations of 1,4-dioxan-2-one

SummaryA new catalytic system, AlEt3-H2O-H3PO4(C), was successfully used as a catalyst for synthesizing poly (1,4-dioxan-2-one) (PPDO) in bulk via the ring-opening polymerization (ROP) of 1,4-dioxan-2-one (PDO). The effects of the molar ratio of monomer to catalyst (M/C), the polymerization temperat...

Description
Summary:SummaryA new catalytic system, AlEt3-H2O-H3PO4(C), was successfully used as a catalyst for synthesizing poly (1,4-dioxan-2-one) (PPDO) in bulk via the ring-opening polymerization (ROP) of 1,4-dioxan-2-one (PDO). The effects of the molar ratio of monomer to catalyst (M/C), the polymerization temperature (T), the reaction time (t) and the water content of monomer PDO (W) were studied systematically. AlEt3-H2O-H3PO4 has been proved to be a very effective catalyst for ROP of PDO. High molecular weights of PPDO can be obtained under following conditions: T=80 °C, M/C = 1311–1573, t=8–10 hours and W
