The introduction into the polymer of small amounts of a solvent (plasticizer) reduces the temperature of glass transition, the yield temperature, and the viscosity of a melt.

{{cite web|url=http://encyclopedia2.thefreedictionary.com/Polymer+Solution|title=Polymer solutions}} An understanding of the thermodynamics of a polymer solution is critical to prediction of its behavior in manufacturing processes — for example, its shrinkage or expansion in injection molding processes, or whether pigments and solvents will mix evenly with a polymer in the manufacture of paints and coatings.

A recent theory on the viscosity of polymer solutions gives a physical explanation for various well-known empirical relations and numerical values including the Huggins constant, but reveals also novel simple concentration and molar mass dependence.{{Cite journal |last=Schubert |first=Dirk W. |date=2020 |title=Novel Theoretical Self-Consistent Mean-Field Approach to Describe the Conductivity of Carbon Fiber-Filled Thermoplastics: Part III—Application of the Concept to Mechanical Properties of Composites and Polymer Solutions |journal=Advanced Engineering Materials |language=en |volume=22 |issue=9 |pages=2000171 |doi=10.1002/adem.202000171 |issn=1438-1656|doi-access=free }}

Applications

Polymer solutions are used in producing fibers, films, glues, lacquers, paints, and other items made of polymer materials. Thin layers of polymer solution can be used to produce light-emitting devices.
