Addition polymerization: It involves following three mechanisms:
1. Free radical polymerization
2. Ionic polymerization mechanism
3. Coordination polymerization mechanism
Free-radical polymerization: It involves following steps:
Initial step
1. Production of free radicals by the decomposition of compounds called initiators
R-R = 2R
Initiator free radicals
The decomposition of the initiator is splitting into two identical fragments called homiletic decomposition, where each fragment carrier's one unpaired electron with it called free radical.
Chain propagation step: The free radical (R) produced in the chain initiation step adds to an alkenes to form a new free radical, which then reacts with additional monomers in a chain reaction:
R + H2C = RCH2CH2
RCH2CH2 +CH2 = RCH2CH2 :CH2

Calculate the ideal rM/rX ratio for cation-anion and anion-anion contacts of an octahedral arrangement of anions around a cation as show in one plane in the figure below.
Bond order is the number of chemical bonds between a pair of atoms. For example, in diatomic nitrogen N≡N the bond order is 3, while in acetylene H-C≡C-H the bond order between the
Atomic spectroscopy: Atomic spectroscopy is the oldest instrumental method of elemental analysis. The origin of these methods dates back to the times of Bunsen and Kirchhoff i
