Recent studies have shown that poly(vinylphosphonate)s are readily accessible by rare earth metal-mediated group transfer polymerization (GTP). This article highlights the progress in this new field and advantages of GTP in comparison to classical anionic and radical polymerization approaches. Late lanthanide metallocenes proved to be efficient initiators and highly active catalysts for vinylphosphonate polymerization yielding polymers of precise molecular weight and low polydispersity. Using this method, our group has developed a surface-initiated GTP to prepare poly(vinylphosphonate) brushes. In combination with different ester cleavage strategies, rare earth metal-mediated GTP is an efficient way to create well-defined high-molecular-weight poly(vinylphosphonic acid).
最近的研究表明，聚（膦酸酯）可以通过稀土金属介导的基团转移聚合（GTP）轻易获得。本文重点介绍了这一新领域的进展，以及与经典的阴离子聚合和自由基聚合方法相比，GTP 的优势。晚期镧系金属茂配合物被证明是乙烯基膦酸酯聚合的有效引发剂和高活性催化剂，可得到分子量精确且低分散度的聚合物。使用这种方法，我们小组已经开发了一种表面引发的 GTP 来制备聚（膦酸酯）刷。结合不同的酯裂解策略，稀土金属介导的 GTP 是一种有效的方法，可以制备具有明确结构的高分子量聚（膦酸）。
