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.

Acrylate end-capped urethane- or urea-based polymers

Hydrogels are provided that include an antimicrobial agent and a cross-linkable urethane-based polymer (CUP). Such hydrogels may be used for the controlled-release of antimicrobial agents as well as in the manufacturing of wound dressings. Wound dressings are provided that comprise a hydrogel as defined herein.

Anti-microbial hydrogel

The present invention relates to poly(alkylene terephthalate) polyesters having long poly-methylene segments and their use in a wide variety of applications. Particularly, said PAT polyesters are used in biotechnological or biomedical applications, wherein the extent of cell adhesion, cell growth or cell interaction, in particular endothelial cells, depends on the odd or even number of carbon atoms in the aliphatic segments. Also provided are methods for the preparation of poly(alkylene terephthalates) (PAT) having long poly-methylene segments, wherein the bifunctional monomers, in particular terephthalic acid (or a derivative thereof) and an aliphatic diol, are dissolved in a solvent and the polycondensation reaction takes place in solution.

Use of poly(alkylene terephthalates) and methods for their preparation

The invention pertains to the technical field of urethane based materials, in particular to radiation curable urethane precursors that are cross-linkable in solid form and materials obtainable therefrom. In addition the invention pertains to methods for manufacturing these precursors and materials, and their uses. The invention is advantageous to the fields of i.e. coatings and biomedical applications.
