Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a bifunctional modified biopolymer based polymer, comprising at least one polymer chain comprising n first functional groups and m second functional groups. The first functional groups comprise groups able of being radically cross-linked following a free radical chain- growth polymerisation.
