Procedure

Using the same procedure as was described in the preceding Examples, 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 73.04 parts of ethyl acetate and 25.11 parts of denatured ethanol. Acetylacetone, 0.5 part, triethylamine, 0.53 part and a 75 percent solution of titanium diisopropyl diacetylacetonate, 0.82 part, were added. The resulting adhesive composition had a solids content of 45% and a viscosity, at 25° C., of 1875 cps. The adhesive properties of the composition were: 0° Shear -- > 24 hours; 180° Peel -- 3.0 lbs. per inch of width; 90° Quick Stick -- 0.52 lb. per inch of width.
