P2 4h synthetic polymers Flashcards
1
Q
what are monomers?
A
small molecules that are linked to form polymers
- each monomers is a repeat unit and are connected via covalent bonds
2
Q
what are polymers?
A
large molecules of high relative molecular mass, made by linking monomers
3
Q
what are polymers used for?
A
everyday materials such as resins, plastics, polystyrene, nylon etc
4
Q
what are the two types of polymers?
A
synthetic polymers and natural or biological polymers
5
Q
what are addition polymers?
A
when the monomer contains C=C bonds and it joins up to make C-C bonded polymers
- joining of ethene monomers
6
Q
how do you name polymers?
A
the name of the alkene with poly as a prefix
7
Q
how do you draw the polymers?
A
the monomer will have a C=C, the polymer has -C-C-
