摘要

Acrylic Acid (AA) was grafted onto LDPE to modify its properties by reactive extrusion process. In this study, a co-rotating twin screw extruder and Banbury were mainly used for the reactive grafting process. By changing the configuration of the screw elements, different degrees of shearing effects gave various degree of grafting. It was found that the ratio of LDPE/AA/DHBP = 100/10/0.5 with a medium shearing in the extruder gave an optimal result, and the ratio of grafted AA was 4.7%, which was measured via a standard titration process.
