the chain length of organosilicone polymers can be controlled by adding $Me_3SiCl$

Vedclass · Answer

(A) $(CH_3)_3SiCl$ is used during the polymerisation of organosilicones because it acts as a chain terminator. When added to the reaction mixture,it reacts with the terminal $-OH$ groups of the growing siloxane chain,forming a stable $(CH_3)_3Si-O-$ group at the end. This prevents further condensation and thus allows the control of the chain length of the organosilicone polymers. Hence,the correct option is $A$.
