    Abstract: The invention relates to a method for producing expandable granulates containing polylactic acid, comprising the following steps: a) melting and mixing the constituents i) between 50 and 99.9 wt. %, relative to the total weight of constituents i) to iii), of polylactic acid, ii) between 0 and 49.9 wt. %, relative to the total weight of constituents i) to iii), of at least one other polymer, iii) between 0.1 and 2 wt. %, relative to the total weight of constituents i) to iii), of a diepoxide or polyepoxide, and iv) between 0 and 10 wt. % of at least one additive, b) mixing v) between 3 and 7 wt. %, relative to the total weight of constituents i) to iv), of an organic blowing agent, into the melted polymer mass, by means of a static or dynamic mixer, at a temperature of at least 40°C, c) discharging the mixture via a nozzle plate with boreholes having a maximum on the nozzle outlet diameter of 1.5 mm, and d) granulating the melted mass containing the blowing agent directly behind the nozzle plate, under water, at a pressure of between 1 and 20 bar. The invention also relates to expandable granulates containing polylactic acid, that can be obtained according to said method, and to special expandable granulates containing polylactic acid, and between 3 and 7 wt. % of an organic blowing agent, preferably n-pentane, and especially preferably iso-pentane. The invention also relates to a preferred method for producing expandable granulates containing polylactic acid and a blowing agent, with a low bulk density.

    Abstract: The invention relates to a method for the production of shaped foam bodies, comprising: provision of a composition having foam particles and binder; introduction of the composition into a space which is bounded on at least one side by a pressing surface; and exertion of pressure onto the composition by means of the pressing surface. The method further comprises irradiation of microwaves through the pressing surface into the composition, while pressure is being exerted onto the composition. The invention furthermore relates to a device for carrying out the method according to the invention, having: at least one pressing surface and a counterbearing surface lying opposite, between which a space extends which is adapted to receive a composition of foam particles and binder. The pressing surface and counterbearing surface adjoin the space directly. The device further comprises at least one stiff layer which locally or entirely is essentially transparent for microwaves and has a surface facing toward the space, which is connected to the pressing surface in such a way as to transmit force. The device also comprises a microwave radiator unit which is arranged on a side of the stiff layer remote from the space and is aligned relative to the space in order to irradiate microwaves into the space through the stiff layer. Lastly, the invention relates to a microwave radiator unit for the heat treatment of foam compositions. The microwave radiator unit comprises a multiplicity of microwave antennas which are arranged in a plane array and at least two of which are connected through a distributor device to a common microwave signal source, which feeds the at least two antennas.
