CONTROL OF SURFACE FUNCTIONALIZATION OF POLYETHYLENE POWDERS PREPARED BY COPRECIPITATION OF FUNCTIONALIZED ETHYLENE OLIGOMERS AND POLYETHYLENE
Additional Document Info
Techniques for functionalization of polyethylene by entrapment of terminally functionalized ethylene oligomers in a host polymer powder or film are described. The effects of varying the oligomer microstructure, the host polymer morphology, and the entrapment procedure on the eventual location of the entrapped nitroxyl groups were examined by ESR spectroscopy and reactivity studies. The results show that the extent of surface functionalization in the product polymer formed in entrapment functionalization can be varied in a controllable and predictable manner. 1989, American Chemical Society.
