PURPOSE:To obtain the titled composition capable of giving a polymer having a low glass transition point, by dimerizing a butane-butene fraction containing n-butene in the presence of a nickel compound and a metallic alkyl halogenate under pressure, subjecting the dimer to the oxo reaction, and hydrogenating the reaction product. CONSTITUTION:After removing butadine, a compound containing oxygen and a compound containing sulfur fully, a butane-butene fraction containing n-butene is dimerized in the presence of a nickel compound e.g. oxygen or sulfur compound of nickel or organic acid of nickel, and a metallic alkyl halogenate of the formula R3Al2X3 or RAlX2(X ia Cl or Br; R is alkyl) under pressure, and the resultant dimer is then subjected to the oxo reaction and hydrogenated to give a 9C alcoholic composition. The composition is then reacted with a compound containing allyl group, e.g. acrylic acid, to afford an isononyl acrylate composition. The resultant composition is then polymerized by the well-known method to give a polymer, having a glass transition point lower than the well-known polymer and improved physical properties, and useful for a tacky adhesive, etc. |
