# Single-Molecule Mixture: A Concept in Polymer Science

## TL;DR

This paper explores the concept of single-molecule mixtures in polymers, showing they may exist in real systems.

## Contribution

The study introduces a theoretical framework for the existence of single-molecule mixtures in polymer systems.

## Key findings

- Model construction and analysis support the existence of single-molecule mixtures.
- Results suggest these mixtures could occur in synthetic or natural polymer systems.
- Theoretical evidence aligns with the chemical space concept in polymer science.

## Abstract

In theory, two extreme forms of substances exist: the pure form and the single-molecule mixture form. The latter contains a mixture of molecules with molecularly different structures. Inspired by the “chemical space” concept, in this paper, I report a study of the single-molecule mixture state that combines model construction and mathematical analysis, obtaining some interesting results. These results provide theoretical evidence that the single-molecule mixture state may indeed exist in realistic synthetic or natural polymer systems.
