Intro To Polymers Flashcards
(7 cards)
1
Q
What is a copolymer?
A
A polymer made of more than one monomer species
They are common - method of tailoring material properties
2
Q
Which types of polymers are thermoplastic?
A
Linear polymers and branched polymers
3
Q
Which type of polymers are thermoset?
A
Crosslinked
4
Q
What does thermoset and thermoplastic mean?
A
Thermoset - does not meant on heating
Thermoplastic - melts and can be remodelled on heating
5
Q
What is polymerisation?
A
Reacting monomers/co-monomers to form a polymer
6
Q
What is condensation polymerisation and what are the byproducts?
A
Step growth reaction
By products usually h2o or low molecular weight alcohols
7
Q
What is addition polymerisation?
A
Chain reaction using free radicals
No by products
Exothermic
AIPT - activation, initiation, propagation, termination
