is used during polymerisation of organic silicones because
(i) the chain length of organic silicone polymers can be controlled by adding
(ii) blocks the end terminal of a silicone polymer
(iii) improves the quality and yield of the polymer
(iv) acts as a catalyst during polymerisation
The answer is the option (i) The chain length of organic silicone polymers can be controlled by adding Me3 and (ii) blocks the end terminal of a silicone polymer.
The length of the chain can be in control by increasing the amount of , which helps in blocking of the polymer ends.
