KCET2018ChemistryPolymers
( ( CH ₃ )₃ SiCl ) is used during polymerization of organosilicons because
Options
- AThe chain length of organosilicon polymers can be controlled by adding ( ( CH ₃ )₃ SiCl )
- B( ( CH ₃ )₃ SiCl ) improves the quality and yield of the polymer
- C( ( CH ₃ )₃ SiCl ) does not block the end terminal of silicone polymer
- D( ( CH ₃ )₃ SiCl ) acts as a catalyst during polymerization
Correct answer
A. The chain length of organosilicon polymers can be controlled by adding ( ( CH ₃ )₃ SiCl )
Step-by-step solution
Silicones are the groups of organosilicon polymers which have ( - (R₂ SiO )- ) as a repeating unit. The chain length of the polymer can be controlled by adding ( ( CH ₃ )₃ SiCl ) which blocks the ends. Silicone
