Abstract
The coloration and material yellowing problem in the production of high-density polyethylene TR580M from different batches are explored and analyzed.TR580M produced in different batches in one year was selected and analyzed by molecular weight and distribution,melt flow rate(MFR),oxidation induction time(OIT),volatile organic compounds(VOC),xylene insoluble matter,ash content and torque detection during processing.The results show that compared to the other batches,the higher TR580M chroma batch has lower ash content,higher xylene insoluble matter and VOC content,and more significant MFR changes at different shear rates and higher torque increases during processing.The main reason for the yellow color is that the residual activity of the catalyst produced in this batch is high,and the insufficient protection of the antioxidant system during the processing leads to the increase of the gel content.关键词
