Graphene core for a golf ball

A golf ball comprising:

• a dual core comprising an inner core and an outer core, the outer core comprising a polybutadiene in an amount ranging from 40 to 90 weight percent of the core, zinc diacrylate in an amount ranging from 10 to 50 weight percent of the core, Zinc oxide in an amount ranging from 1 to 30 weight percent of the core, zinc stearate in an amount ranging from 1 to 20 weight percent of the core, peroxide initiator in an amount ranging from 0.1 to 10 weight percent of the core, and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the core, wherein the core has a flexural modulus ranging from 80 MPa to 95 MPa;
• a mantle layer disposed over the dual core;
• and
• a cover layer disposed over the mantle layer;
• wherein the dual core has a compression value ranging from 40 to 55.
