Disclosed herein is a multi-layer golf ball having a soft outer cover. The golf ball has an inner cover layer with a Shore D hardness of 60 or more, and an outer cover with a Shore D hardness of 55 or less, and more preferably 50 or less. In a particularly preferred form of the invention, the outer cover comprises one or more polyurethane materials. The golf ball of the invention has exceptionally soft feel and high spin rates on short shots of 80 yards or less, and particularly, 40 yards or less, while maintaining good distance and average spin on full shots.

Multi-layer golf ball

Transparent monolithic aerogels based on silica, the bioderived polymer chitosan, and coordinated ions are employed to serve as a three-dimensional scaffold decorated with metal ions such as Au, Pt and Pd ions. It has also been found that the metal aerogels, such as Au(III) aerogels, can be imaged photolytically to produce nanoparticles.

Disclosed is a process to increase adhesion between two adjacent layers. The process comprises roughening the surface of one layer followed by chlorination of the roughened surface and joining of the layers, or treating the surface of one layer with a silicone-based adhesion promoter and joining the layers. In one preferred embodiment the process comprises roughening the surface of one layer, followed by chlorination of the roughened surface, joining of the layers and post-treatment of the molded layers at an elevated temperature for a predetermined time.

New aerogels are disclosed which comprise silica and at least one organic polymer having polar functional groups. Also disclosed are methods for making such aerogels and for making them as substantially transparent objects. In addition, gas detectors, liquid and gas absorbing objects, and optical devices made using these aerogels are disclosed. The present invention concerns optical elements which are substantially transparent and exhibit low refractive indices. The invention further relates to detectors of reactive and absorbate gases based on the physical changes exhibited by the aerogels upon reacting with or absorbing such gases. The present invention further concerns printable objects comprising these aerogels, specifically when the print media are imaged by the absorption of liquid and the spatial localization of pigments or dyes. The invention further concerns reactive gas absorbers comprising these aerogels and the catalytic function the aerogels serve to catalyze subsequent chemical reaction. Furthermore, the present invention concerns the absorption of chemical compounds from condensed states including liquid, critical and supercritical fluids.

The present invention is directed to a golf ball comprising a dual core component, an inner cover layer and an outer cover layer. The dual core comprises an interior spherical center component formed from a thermoset material, a thermoplastic material, or combinations thereof. The dual core also comprises a core layer disposed about the center component, formed from a thermoset material, a thermoplastic material, or combinations thereof. The one or more polyurethane layers are preferably formed via a reaction injection molding (RIM) technique. The inner cover layer is relatively soft and preferably comprises an ionomer or ionomer blend. The outer cover layer is relatively hard and comprises a hard polyurethane. The resulting multi-layered golf ball of the present invention provides for enhanced distance without sacrificing playability or durability when compared to known multi-layer golf balls.

Disclosed herein is a multi-layer golf ball having a soft outer cover. The golf ball has a core, one or more mantle or inner cover layers with a Shore D hardness of 60 or more, and an outer cover with a Shore D hardness of 53 or less. In a particularly preferred form of the invention, the inner and/or outer cover layers comprise a reaction injection molded polyurethane. The golf ball of the invention has exceptionally soft feel and high spin rates on short shots of 80 yards or less and, particularly, 40 yards or less, while maintaining good distance and average spin on full shots.
