    • The invention relates to polymer-containing catalysts (e.g., polymer-containing organo-metal catalysts) that may be useful in various applications (e.g., polymerization of macrocyclic oligoesters). Advantages of these catalysts include the improved ability to prepare, store, and handle the catalyst in open air; higher molar volume and molecular weight; and the ability to produce a blend of reactants and a catalyst (e.g., a macrocyclic oligoester and a polymerization catalyst) for subsequent one-step reaction (e.g., polymerization of macrocyclic oligoesters).
    • 本发明涉及可用于各种应用(例如大环低聚酯的聚合)的含聚合物的催化剂(例如,含聚合物的有机金属催化剂)。 这些催化剂的优点包括提高在露天空气中制备,储存和处理催化剂的能力; 较高的摩尔体积和分子量; 以及产生用于后续一步反应(例如大环低聚酯的聚合)的反应物和催化剂(例如,大环低聚酯和聚合催化剂)的共混物的能力。
