Which of the following may result if an excessive amount of monomer is incorporated into an acrylic resin mixture ?
Correct answer: C. Excessive shrinkage
- A. Excessive expansion
- B. Low impact strength
- C. Excessive shrinkage
- D. Excessive brittleness
Explanation
Excess monomer increases the amount of liquid that must polymerize and therefore increases polymerization shrinkage. It can also weaken the resin, but excessive shrinkage is the best listed effect.
