The effect of maleic anhydride grafting on the flame retardation of plasma pretreated polyethylene

摘要

A rotating cylindrical-type argon plasma treatment system was used for pretreating low-density polyethylene (LDPE) to graft polar vinyl monomers. Maleic anhydride (MA) was used to graft onto plasma-treated LDPE (PLDPE) using UV-induced poly- merization. The MA-grafted PLDPE (MA-G-PLDPE) was characterized by FT-IR spectra, SEM, TGA and ESCA measurement. The modified PLDPE was blended with a commercial flame-retardant additive (FR 44-94S), a coupling agent, lubricant and anti- Oxidant to improve the flammability.
