Summary
Polyketones with indane structure elements were prepared by Friedel-Crafts polycondensation in three different reaction media. Only oligomers or insoluble material could be obtained, probably due to a side reaction of the indane ring, which leads to crosslinking at high conversion. The oligomers are soluble in common organic solvents such as THF and CHCl3. Melting points, glass transition temperatures, and thermal stability of the oligomers were determined.
