Condensation Polymers Flashcards
1
Q
Formation of polyesters
A
dicarboxylic acid + diol
2
Q
Formation of polyamides
A
dicarboxylic acid + diamine
3
Q
Acid hydrolysis of polyamides
A
Add: H2O and hot aq acid => fast reaction
Forms: diammonium ion and carboxylic acid
4
Q
Alkaline hydrolysis of polyamides
A
Add: heat and NaOH/H2O => slow reaction
Forms: diamine(due to deficit of H+ ions) + dicarboxylate salt
5
Q
Acid hydrolysis of polyesters
A
Add: hot aq acid H+/H2O => very slow reaction
Forms: diol + dicarboxylic acid
6
Q
Alkaline hydrolysis of polyesters
A
Add: hot NaOH/ H2O=> very fast reaction
Forms: decarboxylate salt + diol
