3.3.12 Polymers

Question 1

3 methods of forming condensation polymers

Answer 1

Dicarboxylic acid + Diol
Dicarboxylic acid + Diamine
Amino acid + amino acid

Question 2

What is formed in a condensation polymerisation reaction

Answer 2

Small molecule, usually water (HCl)

Question 3

Why are condensation polymers biodegradable

Answer 3

Can be hydrolysed by water. Water is attracted to the polar regions of the polymer

Question 4

Type of bond between Dicarboxylic acid and Diol

Answer 4

Ester linkage (COCO)

Question 5

What part of the carboxylic acid and alcohol react

Answer 5

OH of COOH and H of OH

Question 6

IMFs between condensation polymers

Answer 6

Hydrogen bonds
Dipole dipole
Van der Waals

Question 7

Uses of condensation polymers

Answer 7

Bulletproof vests
Heat protective materials

Due to many Hydrogen bonds

Question 8

Are poly alkenes biodegradable (why/why not)

Answer 8

No
Because they are inert with non-polar bonds

Question 9

How are poly alkenes broken down

Answer 9

Heat
Which can release SO2 and CO2 –> acid rain

Question 10

Pros and cons of recycling

Answer 10

Pros - saves resources
Cons - time consuming to separate and wash polymers
