- Аннотация: We present an in-depth analysis of Raman spectra of novel block copolymers of methylethylene phosphate (MeOEP) with caprolactone (CL) and L-lactide (LA), recorded with the excitationwavelengths of 532 and 785 nm. The experimental peak positions, relative intensities and profiles ofthe poly(methyl ethylene phosphate) (PMeOEP), polycaprolactone (PCL) and poly(L-lactide) (PLA)bands in the spectra of the copolymers and in the spectra of the PMeOEP, PCL and PLA homopolymersturn out to be very similar. This clearly indicates the similarity between the conformational and phasecompositions of PMeOEP, PCL and PLA parts in molecules of the copolymers and in the PMeOEP,PCL and PLA homopolymers. Experimental ratios of the peak intensities of PMeOEP bands at 737and 2963 cm-1 and the PCL bands at 1109, 1724 and 2918 cm-1 can be used for the estimation ofthe PCL—b—PMeOEP copolymers chemical composition. Even though only one sample of thePMeOEP—b—PLA copolymers was experimentally studied in this work, we assume that the ratiosof the peak intensities of PLA bands at 402, 874 and 1768 cm-1 and the PMeOEP band at 737 cm-1can be used to characterize the copolymer chemical composition.
