and for the condensed phase suggest that the solutions of the complexes studied have the same structure, and, hence, the same anisotropy of electronic polarizability (Am) of their objects. Thus the ratio of the anisotropy for the magnetic susceptibilities of the associates, and, in the approximation of axial symmetry, of the remaining complexes (AXm) is approximately equal to the ratio of the mP 0 constants:
The present invention has its object to provide a crosslinkable silyl group-terminated vinyl polymer-containing curable composition which secures a sufficiently long pot life and, at the same time, can be cured rapidly on the occasion of need and can give cured products excellent in thermal stability, oil resistance, weathering resistance, mechanical properties and adhesiveness, among others.
The present invention provides a curable composition containing (I) and (II) mentioned in the following: a vinyl polymer (I) having, on an average, at least one crosslinkable silyl group at its termini, and a photo acid generator (II).
The vinyl polymer (I) according to the present invention is preferably a (meth)acrylic polymer.
