Question

Me₃SiCl is used during polymerisation of organo silicones because

(i) the chain length of organo silicone polymers can be controlled by adding Me₃SiCl

(ii) Me₃SiCl blocks the end terminal of silicone polymer

(iii) Me₃SiCl improves the quality and yield of the polymer

(iv) Me₃SiCl acts as a catalyst during polymerisation

Answer 1

(i, ii) The chain length of the polymer can be controlled by adding Me₃SiCl which blocks the ends of the silicon polymer.
