A new monomer, N-succinimido (N) thiocarbonyl acrylamide is formed whe
n succinic anhydride, thiourea, and acryloyl chloride are condensed in
mole proportions at low temperatures. The monomer is polymerized and
graft copolymerized onto poly (vinyl alcohol) using a potassium bromat
e-thiourea redox system. Acrylamide is also similarly grafted to poly
(vinyl alcohol) using the same initiator system. Grafting efficiencies
of the monomers are determined from the elemental analyses data of th
e graft copolymers. Thermal behavior of the polymers are derived from
the DSC thermograms of the polymers.
