Questions and Answers

What happens to the physical properties of a thermoplastic above its glass transition temperature and below its melting point?

They remain the same

They change drastically without an associated phase change (correct)

They form irreversible chemical bonds

They decompose

What is a defining characteristic of thermoplastics?

They do not melt when heated

They form irreversible chemical bonds during the curing process

They become pliable at elevated temperature and solidify upon cooling (correct)

They fully crystallize below their melting point

How do thermoplastics differ from thermosetting polymers?

Thermoplastics form irreversible chemical bonds during the curing process, while thermosets do not

Thermoplastics may be reshaped when heated, while thermosets do not reform upon cooling (correct)

Thermoplastics fully crystallize below their melting point, while thermosets do not
