<p>A golf ball-forming composition, golf balls prepared from the composition and the process for preparing thereof. The golf ball-forming composition is composed of the following ingredients: polyvinyl alcohol resin 5-80 wt%, filler 0-90 wt%, natural polymer material 0-60wt%, and plasticizer 5-50 wt%. The filler is the common filler known by the skilled person in the art; the natural polymer material is celluloses or amyloses; the plasticizer is the common substances used by the skilled person in the art. The golf ball-forming composition is water soluble biodegradable. The water soluble biodegradable ball's interior is a cavity, and the ball'ssurface is set at least one through drilling connected with the cavity. When the golf ball is hit into water, water will inject into the cavity by the through drilling, which increases the connected area between water and the sphere, accelerates the dissolution of the sphere, and finally makes the sphere biodegrade completely in the environment.</p> |
