Comparison of poly(2-oxazine) and poly(2-oxazoline) isomers reveals that poly(2-oxazine)s are more water soluble, indicating that the side chain has a stronger impact on polymer solubility than the main chain (see image). As such, variations of both side and main chains of poly(cyclic imino ether)s allow accurate tuning of the cloud point temperature in between 94 °C and 11 °C.
