A string-breaking model for phiphi production in the process ..pi../sup -/p..-->..phiphin is discussed. In this model, the ''sequential-pair-creation'' model, it is assumed that the phiphi pair is produced by ss-bar pairs created sequentially: uu-bar..-->..s/sub 1/s-bar/sub 1/..-->..s/sub 1/(s-bar/sub 2/s/sub 2/) s-bar/sub 1/..-->..(s/sub 1/s-bar/sub 2/)(s/sub 2/s-bar/sub 1/)..-->..phiphi. The second ss-bar pair is produced from the breaking of the QCD ''string'' joining the first ss-bar pair. When compared with experiment, the model appears to have problems in describing the data of Lindenbaum et al., and it helps to invoke Breit-Wigner resonances. The cross section for phiphi production obtained from the model indicates that the experimental data may reflect the effects of some sort of enhancement.
