Compressive strengths of alanine-based amino acid ester phosphazenes in comparison to poly(lactic acid-co-glycolic acid) [PLAGA (85 : 15)]. The alanine-based polyphosphazenes presented are poly[bis(ethyl alanato)phosphazene] (PNEA), poly[(50% ethyl alanato) (50% methyl phenoxy)phosphazene] (PNEA₅₀mPh₅₀), poly[(80% ethyl alanato) (20% phenyl phenoxy)phosphazene] (PNEA₈₀PhPh₂₀), and poly[(50% ethyl alanato) (50% phenyl phenoxy)phosphazene] (PNEA₅₀PhPh₅₀). The * indicates results that are significantly different (𝑃<0.05, 𝑛=6). Reprinted from [70] with permission from Elsevier.
