Properties of Polystyrene :
1) It is linear polymer and transparent in nature.
2) It is resistant to alkali and halogen acids.
3) It is soluble in solvents.
Properties of Neoprene :
1) It resembles to natural rubber but it is superior to natural rubber.
2) It does not required sulphur during its vulcanization.
3) ZnO + MnO is added for its cross linking of polymer
.
Properties of teflon :
1)It is highly crystalline linear polymer with high melting point.
2) It is not a true thermoplastic because although its softening point is high but it starts decomposing at its softening points.
3) It is resistance to heat at chemicals and is also insoluble in most of the solvents.
