| Abstract: | The low molecular weight polyethylene is grafted with two different comonomers, methyl methylacrylate and acrylic acid, induced by a radical initiator in a multiphase system under the boilling state of water toluene medium, and the non polar polyethylene is chemically modified by the new approach. The influence of serveral reactional factors on the grafted efficiency and grafted degree is also examined, such as reaction time, reaction temperature, the molar ratio of two monomers and initiator content ect.. |
