Ten variously substituted benzoyl peroxides were synthesized for Raman spectrometric identification both in solution (CCl 2FCClF 2) and solid state. Different to infrared spectra, Raman spectra have been proved to be a useful characterization of the highly symmetric peroxy bond in diacyl peroxides. The ν OO value ranged from 850 to 899 cm -1 varies regularly with the substituent on the phenyl ring.

In this paper, 4-4-(trifluoromethoxy benzoyl cyclohexyl-3, 5-diaminobenzoate with a large branch chain, pyromellitic dianhydride and 4-(4-aminobenzyl) benzenamine were used to synthesize polyimides. The effect of monomer charge order on pretilt angle was investigated for the first time when PIs were used as LC alignment layer, and the effect of diamine mole ratio on pretilt angle was studied. The thermal stability of the pretilt angle was discussed.
