प्रश्न
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.
उत्तर
(i) the chain length of organo silicone polymers can be controlled by adding Me3SiCl.
(ii) Me3SiCl blocks the end terminal of silicone polymer.
Explanation:
The chain length of the polymer can be controlled by adding Me3SiCl which blocks the ends of the silicon polymer.
