抄録

Qualitative analysis of unsaturated polyester resins was performed by referring to the 13C-NMR chemical shifts of 27 kinds of standard linear unsaturated polyesters. The standard polyesters were synthesized from various kinds of dicarboxylic acids and glycols, and were purified with a preparative GPC apparatus. IR, 1H-NMR, and 13C-NMR (frequency 67.8 MHz) spectra of the standard polyesters with over 4 degrees of polymerization were measured and the 13C-NMR chemical shifts of the dicarboxylic acid and glycol components of each standard polyester were summarized. Components which are hard to distinguish by IR and/or 1H-NMR due to coexistence of more than 2 kinds of components can be determined by this method.
