Polymerisation Flashcards
1
Q
How are polyamide formed
A
Reaction between a dicarboxylic acid and a diamine
2
Q
How are polyesters formed
A
Reaction between dicarboxylic acids and a diol producing an ester linkage.
3
Q
Hownis a polypeptide formed
A
Multiple amino acids form pepdltide bond and lose water.
4
Q
Properties of polymers
A
Condensation polymers contain polar bonds such as those in ester and amide links. Hydrogen bonding and dipoles can also form between separate polymers chains.
5
Q
Polyalkenes properties
A
Very inert with non-polar bonds meaning they are not easily broken down. Non-biodegradable
6
Q
Why are polyesters and polyamides biodegradable
A
Can be broken down through hydrolysis due to the polarity within the polymer molecules.
