Condensation Polymers vs Addition Polymers Flashcards
how are condensation polymers made
monomers join to make a polymer a smaller molecule will be removed
how are addition polymers made
monomers join to make polymers –> no other substance formed
what type of molecules are the monomers in condensation polymers
two functional groups
what type of molecules are the monomers in addition polymerss
alkenes C=C
what happens to form polyesters
dicarboxylic acid reacts with diol (both monomers with two functional groups)
and the dicarboxylic acid loses its OH
the diol loses a H
this forms a H2O
However to show they continue to join we remove the OH and H from the outer sides and this makes it 2H2O
what is an addition polymer
alkene which has had high pressure and catalyst to form long chain of them without double bond (poly)
how do we write an equation for forming a polyester
put n infront of both the dicarboxylic acid and diol and then place the polyester as its repeating unit and n on the outside aswell as 2n H2O
