The present invention is directed to restricted or limited flight golf balls. Specifically, new elastomeric blends are provided for forming the cores of one piece or multi-layered balls having the desired reduced coefficient of restitution (C.O.R.) values necessary for restrictive flight performance (i.e. elastomeric blends having C.O.R. values when cured of about 0.560 to about 0.670, with C.O.R. values of about 0.560 to about 0.640 being preferred for the core composition of multi-layered restricted flight golf balls). This is accomplished utilizing the elastomeric blends of the invention without sacrificing the compression (hardness), weight and feel of the resulting cured product. The core compositions can be coated with standard cover stock compositions and/or additional layered compositions when utilized for the formation of multi-layered balls and/or configured with an inefficient dimple pattern to provide restricted flight golf balls having carrying distances about 45-50 yards shorter than that of standard range balls. |
