ELECTRON BEAM INITIATED GRAFTING OF TRIMETHYLOL PROPANE TRIMETHACRYLATE ONTO POLYETHYLENE-STRUCTURE AND PROPERTIES

摘要

Electron beam initiated grafting of trimethylol propane trimethylacrylate (TMPTA) onto polyethylene was carried out over a range of irradiation doses (5-20 Mrad) and concentrations of TMPTA (2-6 parts by weight). The structure of the modified polyethylene was determined using IR spectroscopy, differential thermal analysis and swelling resistance. A correlation between the structure and the tensile and dielectric properties was attempted.
