different types of Polymers

Polymers

large molecule that is made from multiple smaller monomers.

Monomer

Single repeating unit

Additional polymerisation

How alkenes are joined

Removal of double bond from alkene to produce a polymer

Additional polymer structure

Remove c=c

Put bracket around molecule with a small n on bottom right outside bracket

Write the equation for the addition polymerisation of butene

Polymer here is called poly(butene)

Condensation polymers

Condensation polymers can be made by joining together dicarboxylic acid monomers and diol monomers. These monomers are joined together by ester links.

Which two monomers are commonly used for polyesters

Dicarboxylic acid monomer

Diol monomer

When is a polymer referred to as a 'condensation' polymer?

When water is produced as a by-product of the reaction

complete this chemical equation to form a repeating unit of a polyester and water

Two functional groups on either side of the

Long chain of amino acids is called

Polypeptide which folds up to form a protein

Structure of an amino acid

What type of reaction takes place when amino acids combine to form a polypeptide?

Condensation reaction

What name can be used to refer to the bond formed in condensation reaction between amino acids

Amide bond

Peptide bond

Amide link

What do DNA molecules consist of

consist of two polymer chains that coil around each other in a double helix. This helps to protect the DNA from damage

what three elements make up carbohydrates

Carbon

Glycogen

Cellulose

Starch

examples of carbohydrate monomers

glucose

Fructose
