    Abstract: The invention relates to an open-cell, inorganic, aluminosilicate-based foam with a density of less than 25 g/l. The invention also relates to a method f or producing said foam by reacting and expanding an alkali metal silicate solution with an alkali metal aluminate solution, in the presence of a volatile expanding agent and an emulsifier.

    Abstract: In a process for preparing expanded or expandable polymer beads based on biodegradable saturated polyesters made from at least one diol and from at least one dicarboxylic acid,A. polymer pellets are dispersed in a liquid,B. a volatile blowing agent is injected into the dispersion and made to impregnate the pellets at an elevated temperature,C. the pressure on the dispersion is reduced at an elevated temperature, whereupon the pellets comprising blowing agent expand to give foam, and, respectively,D. the pellets are isolated from the liquid.
