Abstract: The present invention relates to a process for the preparation of porous particles comprising at least one polyimide by reacting(A) at least one polyisocyanate having on average at least two isocyanategroups per molecule and (B) at least one polycarboxylic acid having at least two COOH groups per molecule or anhydride thereof,in the presence of at least one solvent, optionally at least one catalyst and optionally at least one further additive, to cause precipitation of a polyimide in the solvent to form the porous particles, to porous particles, obtained with this process, to parts, bodies, foams and/or material comprising these porous particles, and to the use of the porous particles or of the parts, bodies, foams and/or material as insulation material and in vacuum insulation.

Abstract: La presente invención se refiere a un procedimiento para preparar partículas porosas que contienen por lo menos una poliimida por efecto de la reacción de (A) al menos un poliisocianato que tiene un promedio de por lo menos dos grupos isocianato por cada molécula y (B) al menos un ácido policarboxílico que tiene por lo menos dos grupos COOH por cada molécula o anhídrido de éstos, en presencia de por lo menos un solvente, opcionalmente por lo menos un catalizador y opcionalmente por lo menos otro aditivo adicional, a fin de causar una precipitación de una poliimida en el solvente para formar las partículas porosas; a partículas porosas obtenidas con ese procedimiento; a partes, cuerpos, espumas y/o material que contiene esas partículas porosas, y al uso de las partículas porosas o de las partes, cuerpos, espumas y/o material como material aislante y aislación al vacío.
