Polymethylcyclopentadienes and bisdienes exhibit high reactivity with mono- and bisdienophiles in the Diels-Alder reaction.By reaction calorimetry in solution, differential scanning calorimetry, and derivatography it was found that the mono-, bis-, and polyadducts have high thermal stability.The ionization potentials, determined for a series of dienes by photoelectron spectroscopy and spectrophotometry of charge-transfer complexes, lie in the range of 7.15-8.5 eV.The coefficients of the Kuhn-Houwink equation were calculated from data on the characteristic viscosity of the solutions of the polyadducts.They agree with the spherical shape of the polyadducts.The molecular mass of the new polyadducts is greater than 100000.
