Question 5#

Which one of the following is false with regards to silicone?

a. Silicone is a polymer of dimethylsiloxane
b. Short polymer chains form a viscous liquid
c. Long polymer chains produce solid silicone
d. It is found in higher concentrations in synthetic infant milk formulae than in the breast milk of augmented patients
e. None of these is false

Correct Answer is C

Comment:

Long polymer chains produce solid silicone. C is false. While short polymer chains form a viscous liquid, long chains form a cohesive gel. Solid silicone is formed by cross-linking of the polymer chains. While silicone can be found in the breast milk of implanted patients, it is in lesser quantities than in infant formula milk.
