摘要： 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.

摘要： A method for preparing a solid composite material comprising a structural polymer matrix and a thermo-responsive hydrogel involves forming a substantially homogeneous blend of a cross-linkable compound and monomer, oligomer or polymer particles in a blended aqueous liquid, inducing the cross-linkable compound to cross-link to form the thermo-responsive hydrogel and forming the structural polymer matrix from the structural polymer by a further induction means, wherein the resulting solid composite material provides a textile or membrane which presents a thermally insulating layer, through which air and/or liquid water cannot easily pass at low temperatures, but which also provides a more open structure at higher temperatures so that air and moisture vapor can pass through the textile or membrane.

摘要： 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.
