PL - Nylons Flashcards
What are nylons?
Polymers - they are a type of polyamide.
What do all nylons contain?
Amide (-CONH-) links between the monomers.
How many types of nylon are there?
2
What are the two types of nylons?
Nylons made from two types of monomer and nylons made from one type of monomer.
What is the difference between the types of nylons?
Nylons can either be made from one or two types of monomers.
How can nylons be made?
From a condensation reaction (condensation polymerisation).
What is the general structure of the name of nylons containing two types of monomers?
nylon-x,y
x = the number of carbon atoms in the diamine. (The number of carbon atoms between the N atoms in the polymer.) y = the number of carbon atoms in the dicarboxylic acid. (The number of carbon atoms between the C=O groups, plus the C=O carbons, in the polymer.)
e.g. nylon-6,6
How do you name nylons that contain two types of monomers?
Use the general structure: nylon-x,y
x = the number of carbon atoms in the diamine. (The number of carbon atoms between the N atoms in the polymer.) y = the number of carbon atoms in the dicarboxylic acid. (The number of carbon atoms between the C=O groups, plus the C=O carbons, in the polymer.)
What is the general structure of the name of nylons containing only one type of monomer?
nylon-x
x = the number of carbon atoms in the monomer.
How do you name nylons that contain only one monomer?
Use the general structure: nylon-x
x = the number of carbon atoms in the monomer.
What can molecules that contain both an amine and a carboxylic acid group do?
React with themselves in condensation polymerisation reactions to form polyamides.
How can molecules that contain both an amine and a carboxylic acid group form polyamides?
They can react with themselves in condensation polymerisation reactions.
