摘要

Abstract

An aryl dicarboxylic acid amide compound TMB-5 is an efficient

-form nucleating agent for isotactic polypropylene (

PP). Because of the solubility of TMB-5

superstructure and morphology of

PP crystals changed with melting conditions. Effects of final heating temperature (

) on heterogeneous nucleation of

PP/TMB-5 were investigated. It was discovered that the crystallization temperature increased with decreasing

value. The optical microscopic images indicated that when TMB-5 partially dissolved in

PP melt

the remaining (non-dissolved) TMB-5 facilitated the recrystallization of dissolved nucleating agent from the melt

which promoted crystallization. Complete solubility of nucleating agent caused the decreasing efficiency. TMB-5 recrystallized in the form of tiny needles

whose aggregates induced dendritic

PP crystals.
