 Strain-promoted crosslinking of peg-based hydrogels via copper-free cycloaddition patent thumbnailnew patent Strain-promoted crosslinking of peg-based hydrogels via copper-free cycloaddition
The present invention is directed to a covalently crosslinked hydrogel comprising the strain-promoted reaction product of an 8-member cycloalkyne functionalized polyalkylene glycol and a multi-arm glycerol exytholate triazide and methods for making them. Because the precursor materials can be manipulated without causing crosslinking, provided the strain threshold is not reached, these hydrogels permit mechanical control over when (and where) cross linking occurs and are easier to use than prior strain-activated or temperature-activated systems.

Method for hydroformylation of unsaturated compounds


The invention relates to a method for hydroformylation of unsaturated compounds such as olefins and alkynes using mixtures of synthesis gas (co/h2), in which either the unsaturated compounds and a catalyst are heated to a reaction temperature of 60 to 200° c. And the synthesis gas is then added, or the unsaturated compounds and the catalyst are brought into contact with pure co at normal temperature in a preformation step, then are heated to reaction temperature and on reaching the reaction temperature the co is replaced by the synthesis gas.
