To get the silicone of ${\mathrm{R}}_3\mathrm{Si}-{\left({\mathrm{OSiR}}_2\right)}_{\mathrm{n}}-{\mathrm{SiR}}_3$ having four $\mathrm{Si}-\mathrm{O}-\mathrm{Si}$ linkage, the unit taken is

$1$ $\mathrm{mol}$ each of ${\mathrm{H}}_3{\mathrm{PO}}_2, {\mathrm{H}}_3{\mathrm{PO}}_3$ and ${\mathrm{H}}_3{\mathrm{PO}}_4$ will neutralise respectively $\mathrm{x}$ $\mathrm{mol}$ of $\mathrm{NaOH}, \mathrm{y} \mathrm{mol}$ of $\mathrm{Ca}{\left(\mathrm{OH}\right)}_2$ and $\mathrm{z}$ $\mathrm{mol}$ of $\mathrm{Al}{\left(\mathrm{OH}\right)}_3$ (assuming all as strong electrolytes). $\mathrm{x}, \mathrm{y}, \mathrm{z}$ are in the ratio of:
