摘要： Foams of density 0.1 to 1.0 g/cm.sup.3 based on aromatic polyether ketones and other thermoplastic polymers having a high melting point are obtained by melting an intimate mixture of the polymer and from 0.5 to 10% by weight of an aliphatic or aromatic dicarboxylic acid or polycarboxylic acid which suffers a weight loss of 50% or more with elimination of gaseous decomposition products on heating to from 130 to 300.degree. C., and simultaneously cooling and molding the melt.
