Abstract: Production Of Fine-Celled Foams From Sytrene Polymers of the Invention Fine-celled foams are produced by a process in which a styrene polymer is melted, the melt is mixed with a volatile blowing agent and a nucleating agent under superatmospheric pressure, the mixture is let down to atmospheric pressure, and the foam is cooled. The nucleating agent employed comprises from 0.02 to 2% by weight of the calcium salt of a long-chain fatty acid, and from 0.01 to 1% by weight of a finely divided, inorganic substance which is insoluble in the styrene polymer, a mixture of calcium stearate and magnesium oxide being preferred.
