Solvent effects on ester alcoholysis at functionalized polyethylene surfaces Academic Article uri icon

abstract

  • The effects of solvent on the accessibility and reactivity of an ester‐bound fluorophore at a functionalized polyethylene‐solvent interface have been studied. Fluorophore‐labeled polyethylene surfaces were prepared by blending together a small amount of a pyrene esterterminated ethylene oligomer and a host linear low density polyethylene in solution. Films cast from such solutions were then studied by fluorescence spectroscopy to show that a significant number of the entrapped pyrene groups were at the polyethylene‐solvent interface and capable of reaction with soluble reagents. Subsequently, transesterification of these ester‐bound pyrenes using various sodium alkoxides in alcohol, alcohol‐toluene, or alcohol‐tetrahydrofuran solvent mixtures was studied by fluorescence and UV‐visible spectroscopic analysis of the supernatant. The extent of alcoholysis of such esters was found to be significantly affected by the solvent chosen and by the structure of the alcohol. © 1995 John Wiley & Sons, Inc.
