The influence of molecular oxygen and the slip agent, erucamide, on the selectivity of attachment of pyrene to polyethylene chains by >300 nm radiation

The influence of molecular oxygen and a common slip agent, erucamide, on the selectivity of pyrene attachment to polyethylene chains has been investigated. Films with covalently attached pyrenyl groups are useful to follow microscopic changes that occur when the bulk material is perturbed. Selectivi...

Zusammenfassung:	The influence of molecular oxygen and a common slip agent, erucamide, on the selectivity of pyrene attachment to polyethylene chains has been investigated. Films with covalently attached pyrenyl groups are useful to follow microscopic changes that occur when the bulk material is perturbed. Selectivity increases when pyrene-doped low-density polyethylene (PE37) films are thoroughly degassed (
