| Abstract: | Initiated by various photoinitiators,the graft polymerization of acrylamide or acrylic acid onto cornstarch was carried out in inverse emulsion.IR spectrum analysis indicated the formation of grafted polymer.Influences of initiators on polymerization were examined and mechanism of initiation was discussed.With BP as initiator,a low monomer conversion but a high graft efficient could be given.With Irgacure 184 or Irgacure 819 as initiator,a high conversion could be obtained.It is showed that the conversion of acrylamide increases at first and then levels off with the increasing of initiator concentration,while the conversion of acrylic acid decreased at a further elevates initiator concentration. |
