Disclosed herein are polypropiolactone-based polymers, copolymers, and polymer systems, which may be biodegradable and may enhance the recyclability of the polymer system, may be functionalized to introduce a desired functionality into the polymer, and/or may be optionally prepared from renewable raw materials. Novel functionalized beta propiolactones are disclosed. Some novel functionalized beta-propiolactones have functional groups bound to the ring structure of the lactones that provide improved polymer systems. Novel homopolymers of functionalized beta propiolactone are disclosed. Novel copolymers based on functionalized beta-propiolactone and other monomers that copolymerize with beta-propiolactone or with functionalized beta-propiolactone are disclosed. 本文中公开了基于聚丙内酯的聚合物、共聚物和聚合物体系，所述聚丙内酯可以是可生物降解的并且可以增强聚合物体系的可再循环性、可以被官能化以将所需的官能性引入聚合物和/或可以任选地由可再生原料制备。公开了新型官能化β丙内酯。一些新型官能化β丙内酯具有提供改进的聚合物体系的与内酯的环结构结合的官能团。公开了官能化β丙内酯的新型均聚物。公开了基于官能化β丙内酯与β丙内酯或与官能化β丙内酯共聚的其它单体的新型共聚物。
