5.3.4 Polyesters Flashcards
1
Q
What is a polyester?
A
A polymer made of lots of molecules joined in a chain by ester groups
2
Q
What two monomers are needed to make a polyester?
A
A dicarboxylic acid and a diol
3
Q
What is a dicarboxylic acid?
A
A carboxylic acid with -COOH at both ends
4
Q
What is a diol?
A
An alcohol is -OH at both ends
5
Q
Why is making polyesters known as condensation polymerisation?
A
Each time a monomer joins the end of the chain, an H2O molecule is lost
6
Q
Why is a biopolyester?
A
A biodegradable polyester where microbes can use enzymes to break down the polymer
