Poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA)-based brush poly(phosphoamidate)s are successfully synthesized by a combination of ring-opening metathesis polymerization (ROMP) and atom transfer radical polymerization (ATRP) following either a commutative two-step procedure or a straightforward one-pot process using Grubbs ruthenium-based catalysts for tandem catalysis. Compared with the traditional polymerization method, combining ROMP and ATRP in a one-pot process allows the preparation of brush copolymers characterized by a relatively moderate molecular weight distribution and quantitative conversion of monomer. Moreover, the surface morphologies and aggregation behaviors of these polymers are studied by AFM and TEM measurements.
通过开环易位聚合（ROMP）和原子转移自由基聚合（ATRP）相结合的方法，采用基于格拉布（Grubbs）钌的催化剂进行串联催化，按照交换两步法或直接一锅法成功合成了基于聚甲基丙烯酸2-（二甲氨基）乙酯（PDMAEMA）的刷状聚磷酸酯。与传统聚合方法相比，在一锅法中结合ROMP和ATRP能够制备出具有相对适中分子量分布和单体定量转化率特征的刷状共聚物。此外，通过原子力显微镜（AFM）和透射电子显微镜（TEM）测量研究了这些聚合物的表面形态和聚集行为。
