How one can find (δd) the dispersion contribution to δ, (δp) the polar contribution to δ and (δh) the hydrogen bonding contribution to δ, where δ is the Hildebrand solubility parameter?
First thing when starting into something new is to gather basic info through easily available channels. Try to start with a simple Google search Hansen solubility parameter or go directly to Wikipedia.
You will find out that you have to do solubility testing in a range of solvents with large variability of solvent properties and judge good/bad, finally to put in the results into the HSPiP software.
Dear Dr. Sobisch,
I would like to thank you for your answer. I strongly agree with you about going through the basics of the subject of the research field one has aimed at. And, that is why I have come to the point that what the calculation basis behind determination of the values of the Hanson solubility parameters is. The HSPiP software also follows some fundamentals to operate all the calculations resulting in choosing the proper solute/solvent in a specific system. What are the calculation references to find for example, the (δd) of acetone?
My question orients these areas related to the Hanson solubility parameters.
Thank you again for your support.
Best,
I am not sure if it answers your question but there is some discussion of these parameters in this reference.

I suppose that you are looking for a rheoretical calculation.
Indeed each group of your molecule (CH3,CHO) will have lets say deltad, deltap, or deltah value attributed to it. You can find their value tabulated in a reference book. Then you will add them up utilizing a quadratic mixing rule..
Beware, that for large molecules the entropic contribution to the energy of mixing can be very low and therefore you may have a had time finding a good solvent for a polymer no matter how good is the match fo the solubility parameters.
Dear Dr. Byrne,
I would like to thank you for your guidance. This paper is really informative for me and can answer many questions of mine regarding these calculation bases. Thank you very much for your support.

Dear Dr. Havet,
