The present invention is directed to an improved golf ball comprising at least one layer having a siloxane polymer exhibiting a viscosity of at least 1 million centistokes. For a two-layered golf ball, the core and/or cover may comprises a siloxane polymer exhibiting a viscosity of at least 1 million centistokes. For a multi-layered golf ball, the core, intermediate layer, and/or cover may comprise a siloxane polymer exhibiting a viscosity of at least 1 million centistokes.
