Briefly discuss the METALLOCENE COORDINATION POLYMERIZATION [8].
Added by Patience
Step 1
Step 1: Understand Coordination Polymerization – Recognize that coordination polymerization is a mechanism in which a metal catalyst binds monomer molecules (typically olefins such as ethylene or propylene) and facilitates their successive insertion into a growing Show more…

Circle the directing ability and activation for the OH group. ortho meta para activating deactivating b. Write Lewis structure for the electrophile E+ (including all lone pairs and formal charges). c. Write a mechanism for the formation of the MAJOR product. Show curved arrows and include 4 resonance structures for the cationic intermediate. d. Write the mechanism for the loss of a proton from one intermediate to give the product.

The Ziegler-Natta catalyst is used for the synthesis of polymers, according to the scheme below. When ethylene is used the product is polyethylene. What are the possible products when propylene, 1-butene, 2-butene, 2-pentene and cyclohexene are used? Draw the mechanism for the 5 polymerizations. (20 marks)
