The phase transition in the Weinberg-Salam-Glashow (GSW) electroweak theory extended by the majoron and dilaton field is considered. The possibility of the boson condensation in the extreme conditions in the standard electroweak theory is shown. The first order phase transition induces by the radiative corrections (the Coleman-Weinberg potential) in the presence of matter was considered. Due to t-quark mass ($\sim 174\ GeV$) a relatively high Higgs mass ($\sim 313 \ GeV$) was obtained. Only a fraction of this mass is connected to the Coleman-Weinberg potential ($m_{CW} \sim 15\ GeV$). The model produces the first order phase transition for low temperature ($T_c \sim 10\ GeV$). Formation of bubbles filled with matter was considered near the phase transition point. The realistic ball with $ M \sim 10^5 - 10^9 M_{\odot}$ and the radius $ R \sim 10^{12} - 10^{14} cm$ is obtained.
