The samples of poly(n-propyl acrylate), PnPrA, and poly(isopropyl acrylate), PiPrA, were synthesized by free radical polymerization in solution (butan-2-one). The 100 MHz 13C NMR spectra of these homopolymers were recorded in two deuterated solvents: chloroform (CDCl3) and benzene (C6D6). In the PnPrA spectra, the backbone β-methylene carbon signal (β-CH2) (33.0 - 36.5 ppm) was split up to configurational hexads for CDCl3 and C6D6. In the PiPrA spectra, the β-CH2 signal (32.5 - 36.5 ppm) was split up to configurational hexads in both solvents.

Próbki poli(akrylanu n-propylu), PnPrA, i poli(akrylanu izopropylu), PiPrA, otrzymano w polimeryzacji rodnikowej w roztworze. Widma 100 MHz 13C NMR tych homopolimerów zarejestrowano w dwóch deuterowanych rozpuszczalnikach: chloroformie (CDCl3) i benzenie (C6D6). Na widmach PnPrA, zarejestrowanych w deuterowanym chloroformie i benzenie sygnał, węgli metylenowych (β-CH2) (33,0 - 36,5 ppm) ulega rozszczepieniu się na poziomie heksad konfiguracyjnych, natomiast sygnał β-CH2 (32,5 - 36,5 ppm) poli(akrylanu izopropylu) rozszczepia się na poziomie heksad konfiguracyjnych.
