    摘要: The invention relates to the use of a powder made of a polymer, which of two or more components with functionalities suitable for Diels-Alder reactions, or of a powder mixture (dry blend) made of powders respectively of at least one of the reactive components, where these together enter into the Diels-Alder reaction with one another and are capable of a retro-Diels-Alder reaction, in a rapid-prototyping process.The invention further relates to moldings produced with use of said polymer powder through a layer-by-layer shaping process in which regions of a powder layer are melted selectively. The molding here can be removed from the powder bed after cooling and hardening of the regions previously melted layer-by-layer.

    摘要: The present invention relates to innovative materials which can be crosslinked by means of two different crosslinking mechanisms, the first crosslinking mechanism being an irreversible crosslinking. The second crosslinking mechanism is a thermoreversible mechanism.As a result of this thermoreversible change in the arc length, properties of the crosslinked material can be decisively changed and controlled, including flexibility, elasticity and other mechanical properties, but also chemical properties, the gas permeability and vapour permeability and storage capacity of the network. In this way it would be possible, for example, to store energy sources such as fuels.
