Procedure

Using the same procedure as was described in Example 1, an interpolymer of 6.2 parts of acrylic acid, 32.8 parts of methyl acrylate and 61.0 parts of 2-ethylhexyl acrylate was prepared in 73.22 parts of ethyl acetate and 25.11 parts of denatured alcohol, followed by the addition of 0.5 parts of acetylacetone, 0.35 part of triethylamine and 0.82 part of a 75 percent solution, in isopropanol, of titanium diisopropyl diacetylacetonate. The solids content of the adhesive solution was 45% and the viscosity, at 25° C., was 1870 cps. The adhesive properties of the composition were: 0° Shear > 24 hrs; 180° Peel -- 3.0 lbs. per inch of width; 90° Quick Stick -- 0.52 lbs. per inch of width.
