The temperature at which the polymer becomes viscous is called: glass transition temperature (Tg). a) - True b) - false?

a) True

Explanation:

The temperature at which the polymer becomes viscous is called glass transition temperature.

When polymer is heated then it will become viscous and temperature is called glass transition temperature.

Glass temperature depends on the chemical structure of the polymer.

Polymer are made of long change structure and these change are connected together one by one and form a complex structure.

Example - Rubber or elastomer, Plastics.
