Conclusions
-
1.
To determine ways of synthesizing soluble highly unsaturated polymers 1,1-bis(p-ethynylphenyl)-ethane was synthesized. The oligomer formed by its oxidative condensation is soluble in pyridine.
-
2.
The oligomer obtained by the polycondensation of tris(p-ethynylphenyl)methane gives an intense narrow ESR signal, despite the formal interruption of the conjugation in the oligomer chain.
-
3.
As monomers a number of mono-, di-, and tri-acetylenes derived from diphenylmethane and dibenzyl were prepared.
