The telechelic alpha,omega-alkyne-poly(methyl methacrylate) (alkyne-PMMA-alkyne) was synthesized by single electron transfer radical coupling (SETRC) reaction of alpha-alkyne, omega-bromine-poly(methyl methacrylate) (alkyne-PMMA-Br). The propargyl 2-bomoisobutyrate (PgBiB) was first prepared to initiate atom transfer radical polymerization (ATRP) of methyl methacrylate at 45 degrees C using CuCl/l,1,4,7,10,10-hexamethyl triethylenetetramine (HMTETA) as homogeneous catalytic system. Then the SETRC reaction was conducted at room temperature in the presence of nascent Cu(0) and N,N,N',N '',N ''-pentamethyldiethyllenetriamine (PMDETA). The precursor alkyne-PMMA-Br and coupled product alkyne-PMMA-alkyne were characterized by GPC and (1)H NMR in detail.
