  "abstract": "The production of $\\phi$-mesons in proton-proton collisions is investigated within a relativistic meson-exchange model of hadronic interactions. The experimental prerequisites for extracting the $NN\\phi$ coupling strength from this reaction are discussed. In the absence of a sufficient set of data, which would enable an accurate determination of the $NN\\phi$ coupling strength, we perform a combined analysis, based on some reasonable assumptions, of the existing data for both $\\omega$- and $\\phi$-meson production. We find that the recent data from the DISTO collaboration on the angular distribution of the $\\phi$ meson indicate that the $NN\\phi$ coupling constant is small. The analysis yields values for $g_{NN\\phi}$ that are compatible with the OZI rule.",
