In the recent research of our group, stereo-irregular PMMA is crystallized by rapid thermal quenching with chain-stretching agent. Also, extraordinarily extended conformation of PMMA chains in PMMA/benzoic acid binary melts were found in the search for crystallization mechanism. Here, we suggest quick and simple solution processing of 1D hc-PMMA from quaternary solutions with air spray-coating at room temperature. Although 1D hc-PMMAs via spray-coating provided relatively lower crystallinity compared to those from the rapid thermal quenching, its successful preparation supports the crystallization mechanism previously proposed. In solution process, we use quaternary solutions of PMMA/BA/EtOH/H2O by using 80 vol% EtOH cosolvent. Solubility of PMMA in quaternary solutions with BA is higher than in only 80 vol% EtOH cosolvent. 2D correlation analysis was presented to explain why solubility of PMMA is very high in quaternary solutions of PMMA/BA/EtOH/H2O. |
