(a)
Interpretation:
The free radical
Concept introduction:
A process of polymerization in which the growth of chain involves free radicals is known as free radical polymerization. The process includes three steps; the chain initiation step, the chain propagation step and the chain termination step. The minimum amount of energy needed to dissociate a bond is known as the
(b)
Interpretation:
The free radical polymerization for LDPE to form branched polyethylene chain is to be stated.
Concept introduction:
A process of polymerization in which the growth of chain involves free radicals is known as free radical polymerization. The process includes three steps; the chain initiation step, the chain propagation step and the chain termination step. The free radical polymerization is an important process for the formation of variety of products with different structural arrangements.
