Description
Summary:Reversible addition fragmentation chain transfer (RAFT) solution polymerisation of the bio-based lactone monomer γ-methyl-α-methylene-γ-butyrolactone (γMeMBL) has been demonstrated in DMSO and Cyrene. RAFT control was evidenced by control over molecular weights, low disperisites, and kinetic evaluation. Purified P(γMeMBL) homopolymers exhibited high glass transition temperatures (206-221 °C) and excellent thermal stabilities. This work demonstrates the first RAFT solution polymerisation of γMeMBL and the first example of RAFT polymerisation in Cyrene. We report the RAFT solution polymerisation of bio-based monomer γ-methyl-α-methylene-γ-butyrolactone in DMSO and the more sustainable solvent Cyrene.
