查询词典 polyethylene

The suitable reaction conditions are determined by thermal analysis for grafting systems via reactive extrusion technology. The grafted structure and grafted ratio are determined and tested by infrared spectrometry and chemical tritration method. The reaction mechanism, by-reaction inhibition, effect of initiator, and monomer on grafted products are studied extensively.
