Chapter 25- Macromolecules

Polymerisation

The process of joining together a large number of monomers to make a polymer.

Plastics

________ and polymers are non- biodegradable and cause pollution problems.

Macromolecule

A long chain molecule containing hundreds of atoms joined together by covalent bonds.

groups of condensation

There are two ________ polymers: polyamides and polyesters.

Ethene

________ is used to manufacture the polymer, poly (________), commonly known as polythene.

Terylene

________ is made from diol and dicarboxylic acid.

Nylon

________ is made from diamine and dicarboxylic acid.

Monomers

Small repeating units that join to form a macromolecule.

high temperature

At ________ and pressure, thousands of alkenes join together to form an addition polymer.

Addition polymeristion

The type of polymeristion where no atoms are lost so just one product is formed.

Condensation polymeristion

The type of polymerisation where a small molecule, usually water, is also produced as a byproduct.

There are two groups of condensation polymers

polyamides and polyesters

Polyamides

Synthetic polymer of a type made by the linkage of an amino group of one molecule and a carboxylic acid group of another.

Polyester

Synthetic resin in which the polymer units are linked by ester groups.

Biodegradable

Capable of being decomposed by the environment naturally.

Non-biodegradable

Not capable of being broken down naturally (by the action of living organisms.)
