condensation polymers Flashcards
(12 cards)
what are polyamides give an example
formers between a dicarboxylic acid and a diamond
a molecule of water is removed leaving an amide link
nylon-6,6
what is an amide link
-CONH-
how is a polyester formed
dicarboxylic acids and a diol
ester linkage
what’s an ester link
-COO-
how are polypeptides formed
from multiple amino acids
peptide bond
a single monomer can produce a polymer due to the presence of both a NH and a OH group
what is the peptide linkage
-CONH-
give some uses of condensation polymers
bullet proof vests
heat protective materials
why are condensation polymers good for heat protective materials and bulletproof vests
hydrogen bonding and dipoles formed between separate polymer chains holding them together in a strong structure
why are addition polymers not easily broken down by species in nature
they are very intert
non polar bonds
why is it bad to break down addition polymers by burning
produces harmful products such as SO2 or CO
can lead to acid rain
how can polyesters and polyamides be broken down
hydrolysis due to polarity within polymer molecules
why can polyesters and polyamides be put into landfill
they are biodegradable
