The present invention relates to a waterborne polyurethane containing biodegradable segments and the process for synthesizing the same. The waterborne polyurethane according to the present invention has excellent biodegradable, biocompatible and mechanical characteristics and thus is a useful biomedical material, in particular for making films for medical applications.

Biodegradable and biocompatible waterborne polyurethane

Disclosed are a macrocyclic carbodiimide (MC-CDI) and a process for synthesizing the same through condensation of a molecule with multiple-isocyanate terminal functional groups under high dilution in the presence of a phospholene catalyst such as phospholene or arsenic catalyst. Also disclosed are MC-CDI derivatives, such as MC-urea (MC-U), MC-acylurea (MC-ACU), acid functionalized MC-ACU, and anhydride functionalized MC-ACU, processes for synthesizing the same, and the applications of such derivatives as hydrolysis stabilizers in organic polymeric materials, such as polyurethane (PU) and polyesters, as well as the applications in the syntheses of the amide- and imide-modified polyurethane by ring-opening reaction of the MC-ACU.

The present invention relates to a water dispersible polyisocyanate composition bearing urea comprising The present invention also relates to a water dispersible polyisocyanate composition bearing urea and urea derivatives which is obtained by heating the above composition bearing urea for conducting a subsequent reaction, to increase the numbers of isocyanate functional groups contained in said composition, wherein the urea derivatives include biuret, triuret and tetrauret, and most of them are biuret. The present invention further relates to a water dispersible polyisocyanate composition bearing biuret which is obtained by heating the above composition bearing urea for conducting a subsequent reaction, to increase the numbers of isocyanate functional groups contained in said composition. The present invention another relates to an aqueous resin adhesive which contains the water dispersible polyisocyanate composition of the present invention and an aqueous resin containing active hydrogen reactive groups.

Water dispersible polyisocyanate composition and its uses

The inventive system and method simulate the actions of a selected output device driver, and then record all the request and information for the document output. The quality and size of the document output are optimized according to the properties of the selected output device driver and supported resources before it is sent to the selected remote output device. When the document output data is sent to the remote site, it is restored and converted to a format acceptable by the selected output device driver for outputting a document of desired format and quality. The inventive method and system for the universal output driver facilitate the operations of network outputting so that a local host does not have to install the driver of the selected driver. Moreover, the invention can optimize the document output in accordance to the properties of the selected output device, thereby to ensure the quality of the document output and increase the transmission speed.
