Synthesis of polymers via cationic ring-opening polymerization using (NH4)(3)PW12O40-SiO(2)composite catalyst

Composite catalyst of heteropolyacid ammonium salt, (NH4)(3)PW12O40, and SiO(2)was prepared by sol-gel method. The resultant catalyst ((NH4)(3)PW12O40-SiO2, 3.38wt%) having W/Si molar ratio of 2/8 enabled to proceed ring-opening polymerizations of tetrahydrofuran (THF), epsilon-caprolactone (CL), and glycidyl phenyl ether (GPE) to give the corresponding poly(THF), poly(CL), and poly(GPE) having number-average molecular weights (M-n) of 6610, 4010, and 2370 with polydispersity index (M-w/M-n) of 1.57, 1.36, and 1.49 in 24%, 88%, and 59% yields, respectively. Matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) spectra of poly(CL) and poly(GPE) exhibited that Bronsted acid induced from (NH4)(3)PW12O40-SiO(2)is the only one species that initiates the polymerization.
