ABSTRACT:
This invention relates to an improvement in a process for curing unsaturated polyester resins, preferably chemically thickened with a Group II metal oxide or hydroxide, and to the resulting product. The improvement resides in the use of an acetylacetonate ligand of cobalt III, which is mono, di, or tri-substituted with an electron withdrawing group, e.g. a nitro, phenyl or halogen atom.
