Polymers of Life 1: Polymerisation

Question 1

How are polymers formed

Answer 1

When monomers reacts together in the presence of heat or catalyst ( catalytic addition electrophilic ) to a form a macromolecule i.e polymer

Question 2

Definition of copolymer

Answer 2

2 different monomers forming a single polymer structure

Question 3

Definition of polymer

Answer 3

Long chain molecules are made from lots of small molecules joined together

Question 4

Definition of monomer

Answer 4

Small molecules that join together to make polymers

Question 5

What are the two different kinds of polymers

Answer 5

1. Addition polymers

2. Condensation polymers

Question 6

Definition of addition polymerisation

Answer 6

Formation of long chain molecules from lots of small molecules training together with NO OTHER PRODUCTS

Question 7

Definition of condensation polymerisation

Answer 7

Formation of long chain molecules from lots of small molecules joined together with ANOTHER SMALL MOLECULE ( eg. Water ) PRODUCED AS WELL

Question 8

Know how to right a balanced displayed formula equation for polymerisation

Answer 8

Look at sheet

Question 9

How do you name polymers

Answer 9

Take the name of the monomer and add poly eg. Ethene —> poly( ethene ) NOT polyethane

Question 10

Know the difference between and how to draw a:

1. monomer structure
2. polymer structure
3. repeating unit

Answer 10

Look at sheet

1. Monomer = double bond
2. Polymer = square brackets & n
3. Repeating = NO square brackets or n

Question 11

Why are polyalkenes inert ( although can burn )

Answer 11

Due to the absence of of any polar bonds

Question 12

Definition of inert

Answer 12

Non-biodegradable
