This is a derivative of triphenylphosphine allowing to prepare polymer with specific coordination properties towards noble metals.
I would guess in the order of the residual aromatic part of crude oil after firrst distillation = 900-950 kg/m3. Is it difficult to just measure it!?
Thanks. I guess it's not that difficult. But I don't have this product, I just need the density to build a model in order to fit SAXS data made with a copolymer based on this compound. The copolymer has been synthesized through a collaboration.
You can estimate it by the estimation of the molar volume from the group contribution method presented by Fedors* (for low molecular weight liquids) or Van Krevelen** (for high molecular weight polymers ).
