What is it about?
The polysiloxanes are material of great scientific and technological interest. Its applications are very wide, from coatings to elastomeric materials with high impact resistance. In order to understand their properties, it is necessary to analyze them in solution, that is, the interactions of the polymeric chains with those of the solvent.

Why is it important?
Analyzing the behavior of the polysiloxane chains in good solvent has always been of great interest. Remember that the siloxane bond is the most flexible in the field of synthetic polymers, so that the overall conformation, chain size and excluded volume effects are analyzed in terms of the second virial coefficient, which basically contains the information on polymer-solvent interactions.
Perspectives
This work complements those already published related to the physicochemical properties of the polysiloxanes in solution. There has been a particular interest in polysiloxanes that have at least one of the side groups is a long alkyl group, that is, with a number of carbon atoms greater than 5. This has led to an important interest in the theoretical-experimental study of complex polysiloxane molecules that we have named as polysiloxanes with bulky side groups.
