Abstract

Abstract: The polymerizations of ethyl and butyl acrylates with coordination catalyst:Nd(naph)₃-Al(i-Bu)₃ were studied.Kinetic studies indicated that both ethyl acrylate polymerization and butyl acrylate polymerization reaction are first order wtih respect to monomer concentration and 0.5 order to catalyst concentration.The apparent activation energies of EAand BApolymerzation reactions are 17.8 kJ/mol and 33.3 kJ/mol respectively.

Key words: Neodymium compound of naphthenate, Polymerization by rare earth catalysts, Ethyl acrylate, Butyl acrylate
