Single Molecule Mixture: A Concept in Polymer Science

In theory, there exist two extreme forms of substances: pure form and single-molecule mixture form. Single-molecule mixture form contains a mixture of molecules that have molecularly different structures. This elusive form has not yet been explored. Herein, we report a study of single molecule mixture state by a combination of model construction and mathematical analysis, and a series of interesting results were obtained. These results provide theoretical evidence that single-molecule mixture state may indeed exist in realistic synthetic or natural polymer system.
