Abstract

Disclosed is a foamable styrenic polymer gel containing an aqueous blowing agent capable of forming a closed-cell, unimodal foam structure. The gel composes in admixture the flowable melt of a polymer composition having greater than 50 percent by weight of a styrenic polymer and a blowing agent having about 1 percent or more by weight water based upon the total weight of the blowing agent. The styrenic polymer has a degree of water solubility sufficient to ensure formation of a unimodal foam structure instead of a bimodal foam structure. The unimodal cell size distribution provides desirable fabricability and machinability characteristics for the foam structure.
