Question

The straight chain polymer is formed by

• A. hydrolysis of $(C{H}_3{)}_{3}SiCl$ followed by condensation polymerisation
• B. hydrolysis of $C{H}_{3}SiC{l}_3$ followed by condensation polymerisation
• C. hydrolysis of $(C{H}_3{)}_{4}Si$ by addition polymerisation
• D. hydrolysis of $(C{H}_3{)}_{2}SiC{l}_2$ followed by condensation polymerisation

Answer 1

The correct option is D hydrolysis of $(C{H}_3{)}_{2}SiC{l}_2$ followed by condensation polymerisation

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.
