摘要：

In order to synthesize omega-epoxy-functionalized 1,4-polyisoprene omega-epoxy- and alpha,omega-diepoxy-functionalized polystyrenes, anionic living polyisoprene and polystyrene were allowed to react with excess amounts of 2-bromoethyloxirane in THF at -78 degrees C. The resulting polymers were analysed by SEC, H-1 and C-13 NMR spectroscopy, and thin layer chromatography with flame ionization detection (TLC-FID). Both mono- and di-epoxy terminated polymers of controlled molecular weights (2.5 x 10(3)-2.6 x 10(4) g/mol) and of narrow molecular weight distributions were obtained quantitatively with high functionalities.
