Difference between thermoplastic and thermosetting polymers
Thermoplastic polymers
Thermosetting polymers
(1) Thermoplastic polymers are soften and melt on heating.
Thermosetting polymers do not become softer on heating but rather become hard in case prolonged heating is done these start burning.
(2) Thermoplastic polymers can be remoulded recast and resized.
Thermosetting polymers may not be remoulded or reshaped.
(3) Thermoplastic polymers are less brittle and soluble in some organic solvents.
Thermosetting polymers are more brittle and insoluble in organic solvents.
(4) Thermoplastic polymers are formed by addition polymerisation.
Thermosetting polymers are prepared by condensation polymerisation.
(5) Thermoplastic polymers have generally linear structures.
Ex. Polyethylene, PVC, teflon.
Thermosetting polymers have three dimensional cross linked structures.
Ex. Bakelite, urea, formaldehyde, resin.
Electron density vs internuclear distance Electronic density
No, it does not depend upon concentrations of reactants, From the Arrhenius equation, k = Ae^(-Ea/RT) We can say, that it is dependent on activation energy(Ea) and temperatu
From the point of view of "green chemistry" - why should reactions be carried out in CO 2 instead of using carbon monoxide or phosgene (2 reasons)? Apart from the compression of c
