Molecular Weight and Functional End Group Control by RAFT Polymerization of a Bisubstituted Acrylamide Derivative

摘要: Controlled radical polymerization of the bisubstituted acrylamide derivative N-acryloylmorpholine (NAM) has potential to yield telechelic polymers, one end which can subsequently be grafted latex particles. Once grafted, other chain polymer used as an immobilization site for species with applications in molecular biology and biomedicine. The controlled NAM using reversible addition−fragmentation transfer (RAFT) is performed two new agents SC(Z)−SR bearing same functional propanoic acid group (R) different Z groups, benzyl (CTA 1) phenyl 2). RAFT mediated by CTA 1 very fast (>80% conversion less than half hour at 65 °C). linear evolution Mn low polydispersity indices (Mw/Mn < 1.2) are accord expected characteristics a living polymerization. 2 leads broader Mw/Mn's (<1.4). resulting CTA-capped polymers were further amp...
