PL - polymers Flashcards
1
Q
what is addition polymerisation
A
formed from alkenes
the double bond in alkenes ope up and join together to make long chains called addition polymers
2
Q
what is condensation polymerisation
A
usually involves two different types of monomer
each monomer has at least two different functional groups, each functional group reacts with a group on another monomer to form a link, creating polymer chains
each time a link is formed a small molecule (usually water) is lost
polyesters and polyamides
