Polymers Flashcards
How can a commercial plastic be defined as…
A high molecular weight material of organic origin.
How many covalent bonds can carbon form up tp
4
molecular chains are synthesised from low molecular weight compounds called
monomers
The products of the monomer reactions form…
Polymers
What are the three classifications of Polymers
Thermoplastics, Elastomers and thermosets
Polymers are synthesised by reacting monomers at high…
temperatures and pressures
What are the two main polymerisation methods
addition polymerisation, condensation polymerisation
Addition polymerisation is used to polymerise
unsaturated monomers
Thermoplastics consist of molecular chains that are…
linear.
the bonds between the molecules in thermoplastics are very…
weak
raising the temperature of the polymer in thermoplastics increases the amplitude of…
vibration
