Synthesis and polymerization of several unsaturated amides

Abstract EN

New unsaturated amides such as N-substituted acrylamides, crotonamides and cinamamide were synthesized from reaction of unsaturated carboxyiic acide such as acrylic acid, croionic acid and cinamic acid with different primary amines.

All new prepared acrylamide monomers were polymerized easily free radically by using Azobisiso buteronitrile.

N-Substituted crotonamide and N-substituted cinamamide monomers couldn’t polymerized free radically as homopolymerization this is due to steric effect factor of the substituted groups, on the vinylic amide and the allylic acid hydrogen.

Ail prepared monomers were studied by IR, UV spectroscopy and element analysis.

Also the physical properties of the types acrylamide polymers, were studied and the intrinsic viscosity, was measured indicated the high molecular weight.

The shear studying with various solution of polymers were measured.
