Abstract: The invention relates to a process for the production of prefoamed poly(meth)acrylimide (P(M)I) particles which can be further processed to give foam mouldings or composites. A feature of this process is that a polymer granulate is first heated and thus prefoamed in an apparatus by means of IR radiation of a wavelength suitable for this purpose. Said granulate can be further processed in subsequent steps, e.g. in a press mould with foaming to give a moulding or a composite workpiece with foam core.

Abstract: The invention relates to a process for the production of mold-foamed poly(meth)acrylimide (P(M)I) cores, in particular of polymethacrylimide (PMI) cores, which can be used by way of example in automobile construction or aircraft construction. A feature of this process is that polymer granules or polymer powder preheated under pressure are moreover charged under pressure to a compression mold where they are foamed with depressurization. In particular, a feature of the process is that it optionally uses a preferably two-shell compression mold for the heating and also for the cooling of the granules and, respectively, the rigid foam core formed therefrom.

Abstract: The invention relates to a process for the production of mould-foamed poly(meth)acrylimide (P(M)I) cores, in particular of polymethacrylimide (PMI) cores, which can be used by way of example in automobile construction or aircraft construction. A feature of this process is that polymer granules or polymer powder are charged to a compression mould where they are foamed. A particular feature of the process is that said two-shell compression mould has, respectively on both sides, a cavity that conforms to the shape and which serves for both the heating and the cooling of the granules and, respectively, of the rigid foam core produced therefrom.
