Well-controlled reversible addition-fragmentation chain transfer radical polymerisation under ultraviolet radiation at ambient temperature

摘要

Controlled reversible addition-fragmentation chain transfer radical polymerisation of methyl acrylate was carried out under long-wave(lambda >= 365 nm)ultraviolet radiation using an acylphosphine oxide as a photoinitiator at ambient temperature;the polymerisation shows a"living"character at high conversions of polymerisation and leads to well-defined polymers with narrow polydispersities(M_w/M_n < 1.1).
