Indeed, the prepared copolymers are insoluble in dichloromethane, ethanol, tetrahydrofurane but they can dissolve in dimethylformamide.
First, oxidative hydroboration of separated exo-benzyllactol exo-7b, with the hydroborane tetrahydrofurane complex used, afforded a mixture of regio- and diasereoisomeric bicyclic alcohols exo-8b + exo-9b.
At the first step, a mixture of conductive material consisting of 50 % (w/w) graphite, 35 % (w/w) epoxy and 15 % (w/w) hardener was prepared by dissolving in sufficient tetrahydrofurane (THF).
Thermo-optical studies of solutions of asphaltenes in toluene and tetrahydrofurane [22] have shown that the solvent molecules can be trapped during aggregation of asphaltenes resulting in minimum diffusivities (D) before 50 mg/l and an increase in D at higher concentrations until a constant value is reached near 2000 mg/l.
