Synthesis of high molar mass all-(meth)acrylic thermoplastic elastomers by photo-iniferter RAFT polymerisation

Abstract

The synthesis of PMMA-b-PnBA-b-PMMA triblock copolymers using photoiniferter reversible addition-fragmentation chain transfer (PI-RAFT) polymerisation is reported. By utilising a combination of green and blue LED irradiation, copolymers with high molar masses up to M_n ∼ 800 kg mol⁻¹, low dispersities (Ð < 1.25), and thermoplastic elastomer behaviour were synthesised.
