抄録

Analytical technique using infrared spectra was applied to newly synthesized nine kinds of electron beam curing (EBC) type epoxy acrylate resins having the basic chemical structure of AA-(EpH-BPA)n-EpH-AA. The results obtained are summarized as follows : (1) After EBC process, the infrared spectrum of resin varies only at the characteristic bands of AA; the double bonds in the part is found to disappear. (2) AA, MA (metacrylic acid) and CA (crotonic acid) in the partial structure can be distinguished clearly with each other by their characteristic bands. (3) Although the infrared spectrum of EpH (epichlorohydrin) is almost analogous to that of MEpH (methyl epichlorohydrin), they are able to be distinguished from the difference of the ratio of intensities between the 827 cm-1, band (12μm band of epoxide) and the 810 cm-1one of AA.(4) From their general spectral feature, the resins containing BPA and -OOCC16H32COO- can be distinguished with each other. (5) Linear relation is found between the mole feed ratio and the intensity ratio of D1720/D1605. Thus, the technique shown above gives many informations about the structure of the similar type of unknown samples, and the analytical results thus obtained play an important role in the progress of the study about the EBC type resin coating steel plate.
