Macromolecules

Question 1

Definition of macromolecules

Answer 1

A very large molecules that is built up from many small molecules.

Question 2

Definition of Monomer

Answer 2

A small molecule which can be joint together with other monomers to form a polymer.

Question 3

Definition of Polymerisation

Answer 3

The process of joining together a large number of monomers (at least 100 repeated unit) to form a polymer.

Question 4

Addition polymerisation

Answer 4

Addition polymerisation occurs when unsaturated monomers join together without loss of any molecules or atoms.

Question 5

General conditions for addition polymerisation

Answer 5

High temperature (200•C), high pressure (1000 atm), presence of catalyst

Question 6

Condensation polymerisation

Answer 6

Condensation polymerisation occurs when monomers combine to form a polymer, with the removal of a small molecule. (H2O, HCl)

Question 7

Monomers involved in condensation polymerisation have

Answer 7

They have a functional group at each end of the molecule

Question 8

Polyester

Answer 8

A polyester is a condensation polymer containing many ester linkage joining the repeated units together.

Question 9

Polyamide

Answer 9

A polyamide is a condensation polymer which contains many amide linkages joining the repeated units together,
