WebTaking into consideration the temperature (100 °C) and time established for all reactions (24 h), the low molecular weights were attributed to secondary transesterification reactions which took place during the polymerization of monomers that showed higher reactivity than ε-DL, especially L-LA and ε-CL, leading to the generation of polymeric chains with reduced … WebThe ratio of dyes to polymer monomers was 1:130 and the volume fraction of polymers was ˜10%. Segregation is defined as any hydrophobic dye bead being within a cutoff distance from a hydrophobic polymer bead. Almost all condensation occurred on the anionic polymers which formed stretched micelle-like structures with hydrophobic cores.
