Me3SiCl is used during polymerisation of organic silicones because (i) the chain length of organic silicone polymers can be controlled by adding Me3SiCl (ii) Me3SiCl blocks the end terminal of a silicone polymer (iii) Me3SiCl improves the quality and yield of the polymer (iv) Me3SiCl acts as a catalyst during polymerisationSolution:
