Description

Phenazasiline (silylene-bridged diphenylamine)-containing polymers (PPhenaz and PAR) were prepared, and an investigation of the effect of the bridging unit was carried out. The use of polymers as functional additives was also carried out. First, the bridging effect of PPhenaz was investigated by a spectroelectrochemical method. The absorption wavelength derived from the cationic spices, which occurred by the oxidation of PPhenaz was longer than which originated from oxidation of poly(diphenylamine). Next, the use of PPhenaz and PAR as functional additives was studied. Even though only 0.001 phr of PPhenaz or PAR was added, the fluorescence of polymer-added resins was much stronger than that of raw resins, suggesting that the polymers are useful as fluorescence additives in the transparent resin. When PPhenaz and PAR were used as additives simultaneously, the FRET effect from PPhenaz to PAR was observed. When the fluorescence spectra of the dumbbell-shaped resins containing PPhenaz and PAR with compatibilizer (LTI) were measured, the change in this type of FRET was observed by the existence of LTI. We could this improve the method for checking the compatibility of two kinds of resins by using this FRET effect. From these results, PPhenaz and PAR were effective as functional additives in resin.
