The decrease in temperature causes the increase in the density of solvents. Therefore, the concentration of polymers should increase with decreasing temperature. We did not correct this temperature effect in the present study

The 100% and 80% chloroform solutions were transparent, but the 60% chloroform solution was somewhat translucent. Polymer 6 precipitated in the 50% chloroform solution. The intensity of CD spectra was corrected by estimating the concentrations of these samples using the voltage of photomultiplier that corresponds to the UV-vis spectra. Thus, the intensity of the CD spectra in Figure 6 is in arbitrary units and cannot be discussed precisely
