All of the following statements about the differences between self-polymerizing acrylic resins and heat-cured resins are true EXCEPT______________?
Correct answer: D. The former have greater transverse strength
- A. The former have a lower molecular weight
- B. The former have higher residual monomer content
- C. The former are more porous
- D. The former have greater transverse strength
Explanation
Self-cured acrylic has lower molecular weight, more residual monomer and greater porosity, so its transverse strength is lower than that of heat-cured resin. Therefore, greater transverse strength is the false statement.
