organic chemistry - addition polymers Flashcards
1
Q
how is a polymer made?
A
by joining thousands of small, identical molecules. monomers
2
Q
2 types of polymers
A
addition and condensation
3
Q
what are the monomers in addition polymers?
A
alkenes
4
Q
ethene monomers =
A
polyethene
5
Q
what bond does monomers have? polymer?
A
a) double carbon to carbon bond
b) single carbon bonds
6
Q
what is the name of a polymer?
A
poly and then name of monomer
7
Q
how to show a structure of polymer in repeating unit?
A
- take any 2 carbon atoms that are next to each other in chain
- draw these out with hydrogen atoms attached
- place brackets around them and draw small n to the right (n represents a larger number - large number of repeating units)
8
Q
what are the repeating units like in addition polymers?
A
same atoms as the monomer as no other molecule is formed in the reaction. all atoms from monomer end up in polymer
9
Q
what does the repeating unit not contain?
A
a double bond
