15D.3 Flashcards
how does addition polymerization look like
page 132
what is condensation polymerization
the formation of a polymer, usually by the reaction of two different monomers, when another small molecule is formed
what is the two points that make condensation polymerization different to addition polymerization
- each time two monomers join together, another small molecule is formed
- usually two different monomers react together
what is the other small molecule formed in condensation polymerization
either H2O or HCl
to produce a polymer we need
two monomer each with 2 reactive groups (one at each end)
what is the alcohol usually involved in condensation polymerization
a diol
what does a dicarboxylic acid look like
page 132
what is the structure of terephthalic acid
page 132
what is the equation for condensation polymerization
page 133
the monomers in condensation polymerization are attached by
an ester group
how can we represent the structure of a polymer from the product of condensation polymerization
page 133 since the product formed still has reactive groups on both sides so it can continue reacting a form bigger chains until a polymer chain has formed
why can we represent the product of condensation polymerization as a polymer
since the product formed still has reactive groups on both sides so it can continue reacting a form bigger chains until a polymer chain has formed so we can use a polymer structure (not right terminology) to represent it
what is the polymer of terephthalic acid
Terylene
why are dicarboxylic acids used instead of dioyl chlorides
HCl fumes are hazard?? ask miss
how are polyesters formed
the reaction between dicarboxylic acid and terephthalic acid page 132-133
