Question

The straight chain polymer is formed by

• A. hydrolysis of $(CH_3)_3 SiCl$ followed by condensation polymerisation
• B. hydrolysis of $CH_3SiCl_3$ followed by condensation polymerisation
• C. hydrolysis of $( CH_3)_4 Si$ by addition polymerisation
• D. hydrolysis of $(CH_3)_2SiCl_2$ followed by condensation polymerisation

Answer 1

Answer: (D)

Straight chain silanes are silicon oils. These are more stable at high temperature than mineral oils and have less tendency to thicken at low temperature.
