Abstract
An improved golf ball having a coefficient of restitution of at least 0.700 and comprising a hollow, spherical shell of a deformable polymeric material which is filled with either a liquid or a unitary, non-cellular core of a material which, at the time of introduction into the shell, is a liquid. The spherical shell may be solid or cellular. The core material may be added through a hole in the shell as a liquid, a gel or a melt. In the preferred embodiment, the spherical shell is formed from two half shells which are bonded to each other. The mating edges of the half shells may have surface configurations which maximize their contact area.
