通过牺牲合成法合成了结构明确的遥爪开环复分解聚合物。随着可裂解的三嵌段共聚物的形成，实现了对分子量和官能化程度的精确控制。引入可单独处理的可裂解单体，完成顺序脱保护，这开辟了通向在其各自链端具有不同取代基的更复杂的聚合物材料的道路。还提出了牺牲五嵌段和七嵌段共聚物，其允许以良好的产率和显着提高的引发剂效率合成定义明确的遥爪聚合物。
The synthesis of well-defined telechelic ring-opening metathesis polymers has been achieved by Sacrificial Synthesis. With the formation of cleavable triblock-copolymers, precise control over the molecular weight and the degree of functionalization was achieved. Introducing cleavable monomers that can be addressed separately, sequential deprotection was accomplished which opened the path to more sophisticated polymeric materials bearing different substituents at their respective chain ends. Sacrificial penta- and heptablock-copolymers are also presented which allow the synthesis of well-defined telechelic polymers in good yields and significantly improved initiator efficiency.
