The possibilities of the formation of superlight small bipolaron in doped polar insulators have been discussed within t-J{sub p} model derived from Fröhlich and realistic long range Coulomb interaction. Increase of t/J{sub p} dresses the electrons forming polarons and bipolarons. Formation of inter-site (S1) bipolarons is favored by t/J{sub p} ratio. Entropy curves indicate that this formation of bipolarons lead to a more ordered state of the system.
