本文报道了2-亚甲基-1，3-二氧六环(MDO)与功能乙烯基单体控制合成直链和超支化共聚物的第一个例子，通过可逆失活自由基聚合提供了一系列功能可降解的聚合物。共聚反应能够调节以改变可降解链段的加入，以创建具有可预测的摩尔质量、低分散度值的可降解材料，同时还具有侧链官能化。通过差示扫描量热法(DLS)和透射电子显微镜(TEM)分析，证明了二乙二酸二乙酯可以形成纳米粒子，形成可降解的超支化共聚物。
Herein we report the first example of the controlled synthesis of linear and hyperbranched copolymers of 2-methylene-1,3-dioxepane (MDO) with functional vinyl monomers to deliver a range of functional, degradable polymers by reversible deactivation radical polymerization. The copolymerization was able to be tuned to vary the incorporation of degradable segments to create degradable materials with predictable molar mass, low dispersity values while also featuring side-chain functionality. The formation of nanoparticles by the addition of divinyladipate to form degradable hyperbranched copolymers was proven by DLS and TEM analyses.
