C11(Polymers) Flashcards
What is a polymer
A long chain of molecules made from monomers
What is a monomer
Small reactive molecules joined together
What is addition polymerisation
The reaction between alkene monomers to form a polymer
In addition polymerisation the repeating unit has …
-The same atoms as the monomer
-Because when the double carbon bond opens up no other molecule is formed in the reaction
What is condensation polymerisation
-when two different monomers are linked together with the removal of a small molecule
-Condensation polymerisation forms the polymer molecule and one water molecule per linkage
What are usually the small molecules given off in condensation polymerisation
-H2O
-HCL
The monomers used to make the simplest condensation polymers are usually…
Two different monomers with two of the same functional groups on each Monomer
Polyesters are formed from …
-The condensation polymerisation of a diol and a dicarboxylic acid
-with H2O given off in the reaction
How is starch and cellulose formed
When simple carbohydrates polymerise
What is the word equation to form starch
What is the word equation to form cellulose
What is the word equation to form proteins
Amino acids have an …
Acidic and a basic functional group in the same molecule
Amino acids react together during condensation polymerisation to make…
Polypeptides and proteins
What is the word equation to form DNA
