The invention comprises regenerative reactive articles having surfaces useful for decontamination comprising hydrohalide-polyhalides or quaternary halide-perhalide salts corresponding to the formula: ##STR1## wherein X is BR or I; n is an integer of about 5 to 1,000, R is H or a C.sub.1 -C.sub.3 alkyl radical; and the backbone polymer is in the form of a film or fabric. The invention also comprises the process of preparing the said reactive surfaces.

Reactive surface for decontamination

The present invention comprises a hydrocarbon composition consisting essentially of a hydrocarbon and an ionic-association or coordination-complex polymer in an amount sufficient to increase and maintain the elongational viscosity of said composition at a level greater than that of said hydrocarbon alone; said polymer capable of disassociation upon application of a high shear to said composition and reassociation upon withdrawal of a high shear, and to the process for improving the elongational viscosity of hydrocarbons subjected to a high shear regime comprising adding to said hydrocarbon an ionic-association or coordination-complex polymer in amount sufficient to increase the elongational viscosity of said hydrocarbon.
