摘要:
The palladium complex disclosed herein is bis[tri(ortho-tolyl)phosphine] :palladium which is produced by reacting a palladium salt with tri(ortho-tolyl)phosphine and reducing the resultant bis[tri(ortho-tolyl)phosphine] palladium salt with an alcoholic alkali. This complex is useful as a catalyst for the production of 1,3-diene oligomers.

摘要:
An air drying high solid coating composition containing 90% or more of solid components and consisting of (1) 95 - 50 parts by weight of low viscosity alkyd resin having an oil length of 60 or higher and a viscosity of Z.sub.4 or lower, (II) 5 - 50 parts by weight of 1,1-bis-(1'-methyl-2'-vinyl-4',6'-heptadienoxy)-alkane, and if necessary, (III) other components such as pigments, organic solvents and additives. The coating composition is quite effective in the prevention of air pollution and the saving of resources.
