摘要

报告采用光增塑剂可逆加成-断裂链转移（PI-RAFT）聚合法合成了 PMMA-b-PnBA-b-PMMA 三嵌段共聚物。通过结合使用绿光和蓝光 LED 照射，合成了摩尔质量高达 Mn ∼ 800 kg mol-1、分散度低（Ð < 1.25）且具有热塑性弹性体特性的共聚物。

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

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.
