| Abstract: | The relation between physical properties and polymerization conditions of high density polyethylene (HDPE) resin was studied.The technological parameters of the speciality HDPE resin for tubing,grade YEM4803T,were determined through analyses of the effects of reaction pressure,temperature,comonomer and residence time on product's performance.The measurement of physical properties and processing and application tests of the commercially produced speciality resin were carried out.The results indicate that YEM4803T possesses good processing flowability and eminent physical properties. |
