ABSTRACT:
a composition for film formation which can be cured in a short time period and give a film having a low dielectric constant and excellent in heat resistance, adhesion and cracking resistance, a polymer for use in the composition and a process for producing the polymer. The composition prepared by dissolving the polymer having specific repeating units in a solvent has excellent film-forming properties. The polymer has repeating units represented by the following general formula (1):wherein Z and Y are as defined hereinabove.
