Figure Lengend Snippet: a , TGA showing a slightly lower T d of the co-polymer compared with the PS homopolymer. b , DSC showing the same glass transition temperature for the co-polymer and the PS homopolymer. c , DMA showing that the storage modulus E′ and the ratio of loss and storage moduli (tan δ ), which corresponds to the glass transition temperature are similar for this co-polymer and the PS homopolymer.

Article Snippet: However, the DSC thermograms of the co-polymers are devoid of exothermic signals (Supplementary Figs. – ), and the H NMR spectrum recorded after heating PS 49 - co -PHCBI 51 for 30 min under Ar at 180 °C (Supplementary Fig. ) shows no change in comparison to the as-prepared materials, which suggests that the co-polymers have a higher thermal stability than the PHCBI homopolymer.
