Abstract: Radiation-curable low molecular weight partial ester copolymer compositions comprising products of a terminally ethylenically unsaturated compound and a maleic anhydride characterized by having free-anhydride functionality are provided. The partial esters are produced by esterification of certain copolymers with a hydroxyalkyl acrylyl compound, or an admixture thereof with a monohydric alcohol. The compositions of the invention are useful as radiation cross-linkable diluents for radiation-hardenable compositions, particularly in improving adhesion promotion and/or dispersive capabilities of binder resins.

Abstract: Radiation-curable low molecular weight partial ester copolymer compositions comprising products of a terminally ethylenically unsaturated compound and a maleic anhydride characterized by having free-anhydride functionality are provided. The partial esters are produced by esterification of certain copolymers under anhydrous conditions with a hydroxyalkyl acrylyl compound, or an admixture thereof with a monohydric alcohol. The compositions of the invention are useful as radiation cross-linkable diluents for radiation-hardenable compositions, particularly in improving adhesion promotion and/or dispersive capabilities of binder resins.

Abstract: A visual indicating paste composition for producing a detectable color change upon contact with an aqueous solution comprising an indicator dye capable of changing color in the pH range between about 7 and about 11, an inorganic base in the form of a caustic powder dispersed in a liquid carrier capable of absorbing water which is not rapidly leached by water or hydrocarbon, and a minor amount of a boron-containing compound, is provided. When applied to a measuring probe, the paste composition is particularly adapted for detecting the water level in the bottom of tanks and delivery systems containing gasoline, and especially gasoline containing oxygenated blending components, by producing a clear detectable color change without bleeding or run-off upon contact with an aqueous solution. The paste composition exhibits long shelf life and improved water tolerance.

Abstract: Homogeneous molded one and two-piece golf balls exhibiting, improved compression and fracture strength while maintaining desired rebound, click and feel required in a golf ball, are disclosed.

Abstract: A method of preparing hexamethyleneimine which comprises the steps of:A. forming a solution of .epsilon.-caprolactam in a solvent selected from the group consisting of linear and cyclic ethers and polyethers having a boiling point of at least about 100.degree. C, said solution having a concentration of about 1 to 40 percent by weight;B. contacting said solution with gaseous hydrogen in the presence of a catalyst comprising copper chromite and at a temperature of about 150 to 300.degree. C. and a pressure of at least about 1,000 psig, whereby a solution containing hexamethyleneimine is formed; andC. recovering hexamethyleneimine from said hexamethyleneimine-containing solution.
