Abstract: Disclosed herein is a foam ply based on a biodegradable polyester mixture, comprising: i) Substantially from 70 to 5% by weight, based on the total weight of components i) to ii), of at least one polyester based aliphatic and aromatic dicarboxylic acids and on aliphatic dihydroxy compound, and ii) Substantially from 30 to 95% by weight, based on the total weight of components i) to ii), of polylactide, and iii) from 0.1 to 5% by weight, based on the total weight of components i) to ii), of a copolymer which comprises epoxy groups and is based on styrene, acrylates, and/or methacrylates, and iv) from 0.5 to 3% by weight, based on the total weight of components i) to ii), of a nucleating agent selected from the group comprising talc, chalk, carbon black, graphite, calcium stearate, zinc stearate, poly-D-lactic acid, N,N'-ethylenebis-12-hydroxystearamide and polyglycolic acid, and v) from 0 to 50% by weight of inorganic or organic filler. Also disclosed is a process for the production of said foam ply comprising a) mixing, in an extruder at from 160 to 2200C, a biodegradable polyester mixture of components i)-v) as recited above; b) injecting from 1 to 25% by weight of a physical blowing agent in the form of a gas under pressure, and c) cooling and extruding to give the foam ply and, if appropriate, thermoforming in a thermoforming apparatus.

Abstract: Procedimiento para la obtención de piezas moldeadas de material polimérico nanoporoso, que comprende los siguientes pasos: a) preparación de una mezcla polimérica polifásica con dominios en el rango de 5 a 200 nm, b) impregnación de la mezcla polimérica con un agente de expansión, en donde la solubilidad del agente de expansión en la fase que conforma los dominios es al menos dos veces mayor que en las fases adyacentes, c) expansión de la mezcla polimérica polifásica que contiene un agente de expansión, a través de la introducción de la mezcla polimérica en una cavidad, y la expansión dentro de la misma, con lo cual se obtiene la pieza moldeada.
