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