Abstract

The present invention in general relates to acrylate end-capped urethane-based polymers, which are in particular characterized by the presence of at least 3 acrylate end-groups, thereby making them particularly suitable for further processing using multiple kinds of technologies such as 2-photon polymerization, stereolithography (SLA printing), electrospinning, film casting, porogen leaching, extrusion based 3D-printing, spray drying, cryogenic treatment, coatings, cross-linkable micelles, spincoating, and electrospraying.
