Abstract: The test method of automatically timed melt flow rate measurement for ABS and PS was studied,using the melt density data determined by manual method and automatically timed method.Results showed that the precise melt flow rate could be obtaimed easier by the automatic determination of melt flow rate.Compared with the manual method, the error of the result was less than 2%.

Key words: polystyrene, acrylonitrile-butadiene-styrene copolymer, melt flow rate
