Which of the following is correct regarding chemical setting of condensation silicone_______________?
Correct answer: A. Polymerization occurs with repeated elimination of small molecules
- A. Polymerization occurs with repeated elimination of small molecules
- B. Polymerization occurs with elimination of single byproduct
- C. By condensation of repeated molecules of monomers
- D. Condensation does not occur at all
Explanation
Condensation silicone sets by repeated condensation reactions that release a small molecule, chiefly ethyl alcohol, as a by-product. This volatile alcohol is why condensation silicone has greater dimensional change than addition silicone.
