A cured elastomer golf ball component is made by heating an elastomer compound containing an ethylenically unsaturated elastomer, an ethylenically unsaturated monomer, and first and second free radical initiators to a first crosslinking temperature (T1) in a compression mold and partially crosslinking the elastomer, then heating to a second crosslinking temperature (T2) and curing the elastomer component of the golf ball. Either: (i) the first initiator has a half-life of about 0.2-5 minutes at T1, the second initiator has a half-life of about 0.2-5 minutes at T2, and T2 is higher T1 by at least about 30°C; or (ii) the second initiator's one-minute half-life temperature is at least about 30°C higher than the first initiator's one-minute half-life temperature, T1 is within about 20°C of the first initiator's one-minute half-life temperature, and T2 is within about 20°C of the second initiator's one-minute half-life temperature. |
