    Abstract: A process for preparing a polyoxazoline includes feeding continuously an oxazoline, a solvent, and a catalyst to a continuous stirred tank reactor at a rate which provides for a residence time sufficient to achieve ring opening of the oxazoline and polymerize the oxazoline; exiting a polyoxazoline solution from the continuous stirred reactor, the polyoxazoline solution including polyoxazoline, solvent, and, optionally, unreacted oxazoline, low molecular weight oligomeric oxazoline, or a mixture thereof; removing the solvent, and, optionally, unreacted oxazoline, low molecular weight oligomeric oxazoline, or a mixture thereof from the polyoxazoline solution; and recovering the polyoxazoline.

    Abstract translation: 制备聚恶唑啉的方法包括以连续的搅拌釜反应器连续进料恶唑啉，溶剂和催化剂，其速率为提供足以实现恶唑啉的开环并使恶唑啉聚合的停留时间; 从连续搅拌反应器中排出聚恶唑啉溶液，包括聚恶唑啉，溶剂和任选未反应的恶唑啉，低分子量低聚恶唑啉或其混合物的聚恶唑啉溶液; 从所述聚恶唑啉溶液中除去溶剂和任选的未反应的恶唑啉，低分子量低聚恶唑啉或其混合物; 并回收聚恶唑啉。
