For our crosslinkers, we chose EDT due to its non-volatile nature and reasonable stability in air, and EDA as it is commonly used to cure epoxy resins. Amines and thiols were chosen as two candidates both because they are frequently used in commercial epoxy formulations and to compare the effects of different reaction kinetics on the shielded copolymer system. We sought to determine a molecular weight of shielding groups that would facilitate delayed crosslinking of the epoxide groups in the presence of a bifunctional nucleophile without preventing it entirely. In our experiments, we tested a range of effects including varying the DP of grafted chains from 1 to 20, varying the DP of the polymer backbone from 25 to 670, adjusting nucleophilic attack kinetics, and varying the ratio of comonomers from 30 to 70% GMA concentration. The monomers used to form the copolymers and the different crosslinkers in these experiments are represented in Figure .
