摘要
用毛细管流变仪、Rheotens拉伸流变仪、旋转流变仪研究PE-RT管材专用料的流变行为。结果表明:3~#、1~#、4~#、5~#是少量长支链分子和大量线性分子的共混物;2~#具有星型结构,但有少量长支链;6~#具有梳型结构,其分子链上有长支链。
The rheological behaviors of PE-RT speciality resin for pipe were studied with capillary rheometer, Rheotens, dynamic rheometer. The results shows 3 ^# . 1^# . 4 ^# . 5^# are the blend of few long chain branching and linearity. 2^# has the star structure, and a few long chain branch. 6~ is material with comb structure and long-chain-branching.
