316965 \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl}\) is used during polymerisation of organosilicons because

1 the chain length of organosilicon polymers can be controlled by adding \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl}\)
2 \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl}\) improves the quality and yield of the polymer
3 \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl}\) does not block the end terminal of silicone polymer
4 \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl}\) acts as a catalyst during polymerisation.
