Mechanism of Reaction of Polyvinyl Chloride) with Triethylaluminum

GENERAL DESCRIPTION: Triethyl Aluminum is used as a catalyst in Ziegler-Natta polimerization process for vinyl, olefin, diene polymerizations and linear oligomerization and cyclization of unsaturated hydrocarbons. It is also used as a catalyst to produce ethylene gas, chain growth of ethylene, longer chain aluminum alkyls, and in plating Aluminum.
