Abstract: Comminuted polyamide is mixed with 0,5 to 10% of a compound H2NOL-COOR; R being hydrogen, aliphatic, cycloaliphatic or an aromatic radical, and heated above the softening point, but below the decomposition point, of the polamide, but to at least 250 DEG C. to give an expanded product. The polyamide may be linear or crosslinked e.g. by irradiation, by heating with formaldehyde, or by polyfunctional compounds, The mixture of hydroxy alkyl diamine and ester of Specification 858,105 may also be present, and the polyamide formers are the same as in that Specification.ALSO:Comminuted polyamide is mixed with 0,5 to 10% of a compound H2Nlc COO R; R being hydrogen an aliphatic, cycloaliphatic or an aromatic radicle, and heated above the softening point, but below the decomposition point, of the polyamide, but to at least 250 DEG C., to give an expanded product. The polyamide may be linear or cross linked, e.g. by irradiation, or by polyfractional compounds. The mixture of hydroxy alkyl diamine and esters of Specification 858,105 may also be present.
