A zinc acrylate powder coated with a higher fatty acid has a good dispersibility into a rubber, and is used as a co-crosslinking agent in rubber compositions for one piece solid golf balls or for cores of covered solid golf balls. The compositions containing the coated zinc acrylate have a good roll workability and provide solid golf balls having an improved impact resilience, a proper hardness and good sound and feeling of striking.

A golf ball is provided with evenly and uniformly distributed dimples so that six great circle paths on the surface of the golf ball do not intersect any dimples. The spherical surface of the golf ball is divided into 20 identical spherical triangles corresponding to the faces of a regular icosahedron. Each of the 20 triangles is further subdivided into four smaller triangles consisting of a central triangle and three apical triangles by connecting the midpoints of each of the 20 triangles along...

The present application relates to a golf club having a hollowed head portion connected to a hollow shaft portion forming a sealed, internal chamber within the club.
