Fig. 5. Hydrolytic degradation under accelerated conditions (5% KOH) of the different degradable polymer prodrugs as a function of the MPDL fraction and the nature of the methacrylic ester monomer: (a) Gem-P(OEGMA-co-MPDL); [black circle], control (F_MPDL = 0); ▲, P1 (F_MPDL = 0.06); ■, P2 (F_MPDL = 0.12); [blacktriangledown], P3 (F_MPDL = 0.25). (b) Gem-P(MMA-co-MPDL); [black circle], control (F_MPDL = 0); ▲, P4 (F_MPDL = 0.10); ■, P5 (F_MPDL = 0.19); [blacktriangledown], P6 (F_MPDL = 0.29). Dashed lines are guides for the eye only.
