Name two types of Polymerisation
Condensation Polymerisation Addition Polymerisation
What product is produced in addition to the polymer in a condensation reaction?
Water (H20)
What type of bond must be broken for addition polymerisation to occur?
C=C Bond
How many functional groups must be on each monomer for condensation polymerisation to occur?
2
Why are polyalkenes so unreactive?
Because they have strong non-polar C-C and C-H bonds
What bond is repeated in a Polyester?
-O-CO-
What 2 monomers must react for a polyester to form?
a diol and a dicarboxylic acid
What 2 monomers must react for a polyamide to form?
a dicarboxylic acid and a diamine
What type of polymer are proteins?
Polyamides
What are the issues with disposing of polyalkenes by combustion?
• CO2 is produced - Toxic CO is produced
What reaction occurs when polyamides are biodegraded
Hydrolysis
