Isoprene (2-methyl-1,3-butadiene) is the monomer for natural rubber. Natural rubber is formed through cationic addition polymerisation. Cationic addition polymerisation is catalysed by acids and Lewis acids. Alkenes containing electron-donating groups usually undergoes cationic addition polymerisation.
The components of Zeigler Natta catalyst, used in the polymerisation of propylene, are:
TiCl3 + Al(C2H5)3
TiCl4 + Al(C2H5)3
Ti(C2H5)3 + AlCl3
Ti(C2H5)4 + AlCl3
Teflon is a polymer of :
tetra fluoroethylene
tetrabromoethylene
tetraiodoethylene
tetrachloroethylene
