in free radical polymerization, wastage reaction are due to

Expert Solution

Ans- in free radical polymerization wastage reaction is Due to side reactions and inefficient synthesis of the radical species, chain initiation is not 100%. The efficiency factor, f, is used to describe the effective radical concentration. The maximum value of f is 1.0, but values typically range from 0.3-0.8. The following is a list of reactions that decrease the efficiency of the initiator.

Primary recombination: Two radicals re-combine before initiating a chain. This occurs within the solvent cage, meaning that no solvent has yet come between the new radicals.

Other recombination pathways: Two radical initiators re-combine before initiating a chain but not in the solvent cage.

Side reactions: One radical is produced instead of the three radicals that could be produced.

With the aid of diagrams describe the radical polymerization of vinyl acetate using AIBN as initiator. Describe initiator formation, monomer initiation, and propagation steps. In addition, describe the various mechanisms by which chain termination (no capacity for further growth) can occur. Describe the various ways in which charge transfer could occur (potential for further growth) for the polymerization described in part (b) above.

The living character of living radical polymerization is limited under certain conditions, such as high monomer conversion, high initiator concentration, and high targeted molecular weight (>100,000). Explain why these conditions result in broadening of PDI and some difficulty in producing block copolymers with well-defined block lengths of different monomers.
