Calculated rate constants for the nonautocatalytic and autocatalytic pathways of the degradation of linear polymer at room temperature (see Fig. S14–S16)^a.

Trigger	k 1 (min−1)	k 2 (M−1 min−1)	k 2 c 0 (min−1)
0.5%	2.1 × 10−4	0.28	6.7 × 10−3
1%	1.4 × 10−3	0.19	4.3 × 10−3
5%	1.8 × 10−3	0.23	5.6 × 10−3

^aRate constants k₁ and k₂ are defined in text, c₀ is initial concentration of degradable group. Concentration (M) is [Fmoc]. See ESI for additional details of the kinetic fit. The 1 mol% run was repeated and values found within 20%, establishing reproducibility.
