2-亚甲基-1,3,6-三辛烷（MTC）在自由基引发剂的作用下通过开环聚合得到了可生物降解的聚酯。MTC还能与苯乙烯、醋酸乙烯、甲基乙烯酮、n -乙烯基-2-吡罗烷酮、n -异丙基丙烯酰胺和马来酸酐等乙烯基单体共聚。在自由基引发剂的作用下，MTC与这些乙烯基单体共聚，可以得到各种以酯基为主链的可生物降解聚合物。此外，所得共聚物还具有光解、水溶性、热敏性、洗涤剂助剂和吸水性等功能。
2-Methylene-1,3,6-trioxocane (MTC) was polymerized via ring-opening in the presence of a radical initiator and the obtained polyester was biodegradable. MTC could also copolymerize with various vinyl monomers such as styrene, vinyl acetate, methyl vinyl ketone, N-vinyl-2-pyrrolidone, N-isopropyl acrylamide, and maleic anhydride. By copolymerizing MTC with these vinyl monomers in the presence of a radical initiator, we could obtain various biodegradable polymers with ester group introduced into the backbone. In addition the obtained copolymers exhibit certain functionalities such as photolysis, water-solubility, thermosensitivity, detergent builder, and water-absorbability.
