Abstract

Abstract: ：The surface tensions of polymers with different molecular structure and molecular weight have been measured using a polymer melt suspending drop instrument. The dependence of surface tension on the molecular structure and molecular weight has been summarized. Besides other variables, the influence of chemical constitution was considered, the derived relationship was more appropriate polymer systems than traditional ones.

Key words: polymer, surface tension, molecular constitution, melt suspending drop
