摘要：

A melting-point depression analysis of high-density polyethylene crystals embedded in molten branched polyethylene is presented. The results indicate that the melting temperature of the crystals is influenced by both the branching content of the low-density polyethylene and the relative volume concentration of the two polymers. The results are critically disscussed in terms of the Flory-Huggins approximation for polymer-polymer mixtures.
