Next, polymers with PEGMA500 shielding units (~10 repeat units) were varied from 30 to 70 mol% shielding monomer content while keeping the total epoxide group concentration in solution constant at 1 M (Figure ) with EDA. When the shielding group concentration was 30 and 40 mol %, the material crosslinks rapidly and reaches final G' values on the order of 10 5 Pa. At 50% concentration of shielding groups, the material reaches a lower final modulus on the order of 10 4 Pa. At the maximum tested 70% molar ratio of shielding group to reactive group, the shielded polymers still form a gel, but do not attain an equilibrium modulus during the experimental timeframe. The PEGMA500 shielding groups do not provide a sufficient steric barrier to reaction but do provide some hinderance to reaction evidenced by the decreased final modulus values compared to control samples.
