Analysis of cloud points and clouding curves by varying heating rates using a commercially available automated melting point apparatus is a method to obtain a corrected cloud point for polymers that have a lower critical solution temperature (LCST). Such assays also provide information about the effects of varying heating rates on LCSTs and similar stimuli-responsive phase separation behavior. This melting point apparatus makes it experimentally simple to conduct such assays that probe the effect of varying heating rates, the effect of polymer structure, and the effect of solution components on the breadth and progress of the phase transition process over a wide temperature range. 2007 Wiley Periodicals, Inc.
