summary lecture 5

Answer 24

Free radical polymerisation

• Initiation – homolysis, single electron transfer
• Propagation – Head to tail v head to head
• Combination and Disproportionation
• Chain Transfer

Anionic Polymerisation

• Absence of termination
• Experimental criteria for living polymerisations
• Ring-opening polymerisation
