need help on polymer chemistry question
Determine which polymerization mechanism(s), i.e. radical, anionic, and cationic, can be used for the following monomers. Briefly explain your answer.
Homework Answers
Solution:
1) CH2=CHCl :
Vinyl chloride undergo free radical polymerization to produce poly vinyl chloride polymer. Therefore, more suitable mechanism is free radical polymerization.
2) CH2 = CHCN
Vinyl cyanide undergoes anionic polymerization more frequently due to presence of strong electron withdrawing CN group.
3) CH2=C(CN)2
Due to presence of two electron withdrawing groups (CN), above monomer form polymer via, anionic polymerization.
