|
|
KETONE |
An organic functional group Comprised of a Carbonyl Group attached to two H/C groups Named by counting carbons for root name, drop 3, add -one Used as solvents because they easily dissolve many other organic molecules, esp polar. 400 |

THERMOSETTING POLYMER |
Polymers that do NOT change shape when heated. |
|
|
VULCANIZATION |
process in which sulfur is added to rubber, creating strengthening, disulfide links. 398 |
