Representative Gel Permeation Chromatography data for the P(SM) tapered segment (purple), P(SM-M) tapered copolymer (blue), P(I-IS-S) tapered diblock copolymer (red), and P(I-IS-S-SM-M) tapered triblock copolymer (green). The number average molecular weights and polydispersity indices of TBCs were determined using a Viscotek 270Max instrument fitted with Waters Styragel HR1 and HR4 columns in series, operated with THF as the mobile phase, and calibrated using polystyrene standards.
