Rapid and Systematic Access to Quasi‐Diblock Copolymer Libraries Covering a Comprehensive Composition Range by Sequential RAFT Polymerization in an Automated Synthesizer

A versatile, cost-effective approach to the rapid, fully unattended preparation of systematic quasi-diblock copolymer libraries via sequential RAFT polymerization in an automated synthesizer is reported. The procedure is demonstrated with the synthesis of a 23 member library of low dispersity poly(butyl methacrylate)-quasiblock-poly(methyl methacrylate) covering a wide (fivefold) range of molar mass for the second block in a one-pot, sequential, RAFT polymerization.
