Sulfonation of Low-density Polyethylene and Its Impact on Polymer Properties

Sulfonation of polymers is of great importance for the packaging industry mainly due to its effect on the alteration of surface functionality of polymer films. In this study we customized liquid phase sulfonation of low-density polyethylene (LDPE) swelling the polymer by using a combination of polar...
