Process for making hydrophilic polyethylene |
| abstract |
A process for grafting acrylamide onto the surface of low density polyethylene (LDPE). The LDPE is first oxidized by a chromic acid solution and then reduced with diborane to produce a hydroxyl-rich surface. Acrylamide is then grafted onto the surface of the LDPE by free-radical initiation, resulting in a hydrophilic polyacrylamide layer covalently bonded to the LDPE. The process has no effect on the bulk properties of the LDPE. |
