Flashcards in Polymers and Synthesis Deck (12):
1

What are the two types of polymerisation?

Addition and condensation.

2

Alkenes open up their double bonds to form...

addition polymers

3

What are polymers?

Long chain molecules formed when lots of small molecules called monomers.

4

What is condensation polymerisation?

A small molecule (often water) is lost as the molecules link together.

5

Give three examples of condensation polymers.

Polyesters, polyamides and polypeptides.

6

What does each monomer in a condensation polymer have?

At least two functional groups.

7

What is formed between the monomers of a polyester?

An ester link (-COO-)

8

What is formed between the monomers of polyamides and polypeptides?

Amide links (-CONH-) (peptide bonds)

9

What is hydrolysis?

When the ester or amide link is brown down by a reaction with water in an acidic or alkaline solution.

10

Give an example of a biodegradeable polymer.

Poly(lactic acid)

11

What is a photodegradable polyamide?

Condensation polymers that contain C=O (carbonyl) groups can be broken down by light as the C=O bond absorbs ultra violet radiation and the energy can cause bonds to break

12

What is a condensation polymer?

Monomers join and form chainAND form H2O or HCl or something
