-Polymers have very long molecules that form a tangled mass, rather like spaghetti. This means that they are strong whilst being flexible,
-Using different monomers (e.g Ethene, methene) to create a polymer gives it different properties,
-Thermosoftening polymers have weak intermolecular forces between their molecules, therefore, when heated they soften and when they cool down, the harden again, this means that they can be heated to mould them into a shape more than once!
-When thermosetting polymers are heated for the first time, chemical bonds form between the polymer molecules, they link together in a giant network and they can NOT be remoulded again... but they set hard!
-Polymers have very long molecules with strong bonds holding the atoms together within the molecules,
REMEMBER:
Chemical bonds= stronger, make new compounds. Intermolecular forces= weaker, non permanent bonds.
