| 摘 要： | Low molecular weight poly（glycidyl methacrylate）s （PGMAs） were prepared by photopolymerization in ethyl acetate, with benzophenone （BP） as photoinitiator, and triethylamine （TEA） as hydrogen donor. The existence of semipinacol dormant end groups in PGMA was confirmed by FT-IR and ^1H-NMR, and the content of the semipinacol dormant groups was determined quantitatively by ^1H-NMR measurement. The effects of various thctors, such as reaction time, BP concentration and monomer concentration on the synthesis of the polymers were investigated systematically. The molecular weights of the polymers were also investigated with GPC. It is shown that increasing BP concentration and decreasing irradiation time and monomer concentration led to a significant decrease of the molecular weights.

| Abstract: | Low molecular weight poly(glycidyl methacrylate)s (PGMAs) were prepared by photopolymerization in ethyl acetate, with benzophenone (BP) as photoinitiator, and triethylamine (TEA) as hydrogen donor. The existence of semipinacol dormant end groups in PGMA was confirmed by FT-IR and 1H-NMR, and the content of the semipinacol dormant groups was determined quantitatively by 1H-NMR measurement. The effects of various factors, such as reaction time, BP concentration and monomer concentration on the synthesis of the polymers were investigated systematically. The molecular weights of the polymers were also investigated with GPC. It is shown that increasing BP concentration and decreasing irradiation time and monomer concentration led to a significant decrease of the molecular weights. |
