Abstract From the Canadian patent

Curable polyester resin compositions of unsaturated polyester resin and organoaluminum compound dissolved together in a vinyl monomer liquid. Viscosity characteristics of such liquid compositions are regulatable by such organoaluminum compound addition. Cured product resins display improved chemical resistance. The liquid polyester resin compositions of this invention enable, one to avoid or to substantially proven the so-called "running" and "sagging", of polyester liquid resin compositions during their application in use situations such as lay-ups with fibre glass, and the like where stay put characteristics, are desirable.
