Effect of Addition of Poly（Phenazasiline） to Plastic Blends for Fluorescent Properties and Impact Strength

Abstract

Effects of addition of poly(phenazasiline) (PPhenaz) to plastic blends were investigated. PPhenaz was blended with poly(lacticacid) (PLA), poly(ε-caprolactone) (PCL), and lysine triisocyanate (LTI), then the blend composites were molded. The PPhenaz containing blend composites showed strong fluorescence. Fluorescence λ_max of the PPhenaz containing blend composites were not changed by addition of LTI. This fluorescence behavior was different from that resulting from addition of dibenzazepine-containing polymer. Addition of PPhenaz to PLA/PCL/LTI blend composite improved impacts trength. These results suggested that PPhenaz was usuful as a functional additive for plastic blends.
