专利号:WO-2023152730-A1 优先权日:2022-02-14 标题 :Amine-borane adducts in the synthesis of polyester and its copolymers using cyclic esters and compositions thereof 发明人:FENG XIAOSHUANG; LIU JINGJING; GNANOU YVES 权利人:UNIV KING ABDULLAH SCI & TECH 摘要:Embodiments of the present disclosure provide for the process of synthesis of polyester and its copolymers through (co)polymerization of cyclic esters and with other oxygenated monomers using amine-borane adduct. Embodiments of the present disclosure further describe the controlled anionic ring-opening polymerization of the cyclic compounds. Embodiments of the present disclosure also describe the polymerization of cyclic compounds using the synergistic effect of amines and thioureas. Embodiments of the present disclosure also describe compositions of polymers formed by the said process.
