An isononyl acrylate monomer composition of acrylates of C.sub.9 alcohols obtained by a hydroformylation and a hydrogenation of C.sub.8 olefins obtained by a dimerization of a butane-butene fraction containing n-butene separated from butadiene which comprise 3 to 20 wt. % of olefins having one isobutane skeleton and less than 3 wt. % of olefins having quaternary carbon and more than 90 wt. % of a total of n-octenes, monomethylheptenes and dimethylhexenes and 0.8 to 2.0 of a ratio of a total of n-octenes and monomethylheptenes to dimethylhexenes.

Isononyl acrylate monomer composition

An aliphatic, cycloaliphatic or aromatic polyol is incorporated in a catalyst of an organoaluminum halide and a nickel compound. The catalyst is used for a dimerization or codimerization of a lower monoolefin to improve a reaction velocity and a stability in the reaction.
