Which statement is true regarding thermoplastic glassy polymers mixed with plasticizers? A) They eliminate internal stresses. B) They reduce the transition temperature from the glassy state to a flexible state. C) They increase the transition temperature. D) They enhance the stiffness of the polymer.
Understand the Problem
The question is asking us to identify which statement accurately describes the behavior of thermoplastic glassy polymers when mixed with plasticizers. We need to evaluate each option in relation to the effects of plasticizers on the properties of these polymers, particularly their transition temperatures and internal stresses.
Answer
They reduce the transition temperature from the glassy state to a flexible state.
The final answer is they reduce the transition temperature from the glassy state to a flexible state.
Answer for screen readers
The final answer is they reduce the transition temperature from the glassy state to a flexible state.
More Information
Plasticizers are added to thermoplastic polymers to lower the glass transition temperature (Tg), making the polymers more flexible at lower temperatures. This is particularly useful for improving the processing and flexibility of the materials.
Tips
A common mistake is assuming plasticizers increase Tg or stiffness. They lower the temperature at which the polymer transitions to a more rubbery and flexible state.
