FIELD: chemistry.
SUBSTANCE: invention concerns expandable polyamide composition consisting basically of: (A) compound with at least one isocyanate group, possible blocked one, (B) polyamide, and (C) compound with at least one acid group, preferrably carboxyl one. The invention also concerns production of polyamide foam from the said composition and the foam produced in this process. The said process allows obtaining foam directly from the said composition, i.e. without addition of any extra compounds, as well as foaming reaction control. Moreover, according to the invention, this foam has regular cell distribution conforming to the closed type and can be applied in various fields, e.g. in thermal or sound insulation and saddlery.
EFFECT: obtainment of foams of various types and properties.
