Abstract
Isopropanol (ISP)-Ag(I) photoinitiator has been used for the kinetic s tudy of polymerization of a non-conjugated divinyl monomer N,N'-methyl enebisacrylamide (MBA). Rate of polymerization was found to proportion al to [MBA](1.50), [ISP](0.43), [Ag(I)](0.50) and I-a(0.50). Formation of an adduct between Ag(I) and ISP followed by its excitation, decomp osition of the excited adduct to give initiating ketyl radicals, intra -molecular cyclization of monomer radical prior to propagation and mut ual termination is proposed as possible mechanism and discussed.
