Abstract

A method for reducing the adherence of a High Internal Phase Emulsion (HIPE) to belt surfaces in a multi-tiered curing oven is provided. The method comprises forming a High Internal Phase Emulsion from an oil phase comprising monomer, cross-linking agent, emulsifier, an aqueous phase and photoinitiator; depositing the High Internal Phase Emulsion on an extrusion belt; exposing the High Internal Phase Emulsion to an Ultraviolet light source to partially polymerize the top surface of the High Internal Phase Emulsion; moving the High Internal Phase Emulsion to a multi-tiered curing oven such that the partially polymerized top surface of the High Internal Phase Emulsion is contacted with a curing oven belt in the multi-tiered curing oven; and polymerizing the monomer component in the oil phase of the High Internal Phase Emulsion at a temperature of from about 20° C. to about 150° C. for a time sufficient to from a High Internal Phase Emulsion foam.
