Abstract
An orthopaedic bandage is described which comprises a support carrying a vinyl compound, which compound polymerizes when exposed to a water-activated vinyl polymerization catalyst. The vinyl compound is a hydrophilic prepolymer which contains more than one polymerizable vinyl group. This prepolymer is in association with at least one component of a water-activatable vinyl polymerization redox catalyst in solid form in a water pervious coating which is insoluble in the prepolymer. Encapsulation of one component of the catalyst system in a water pervious coating provides a storage stable bandage which is activated by immersion in water and gives a satisfactory working time for immobilizing a limb compared to use of an uncoated catalyst.
