the chain length of organosilicon polymers can be controlled by adding $\left(\mathrm{CH}_3\right)_3 \mathrm{SiCl}$

$\left(\mathrm{CH}_3\right)_3 \mathrm{SiCl}$ improves the quality and yield of the polymer

$\left(\mathrm{CH}_3\right)_3 \mathrm{SiCl}$ does not block the end terminal of silicone polymer

$\left(\mathrm{CH}_3\right)_3 \mathrm{SiCl}$ acts are as a catalyst during polymerisation
