Polymer materials are utilized in an increasing number of categories of products, such as components for cars, boats, airplanes, within the electronics industry and other advanced industry as well as in paints and other coatings, for special packaging etc. The uses of polymer materials in new categories of products are only limited by the product properties. It is thus a continuous need for development of polymer products with improved properties e. g. with respect to increased scratch resistance, improved weather resistance, increased UV resistance, increased chemical resistance and improved properties with respect to antioxidation, anticorrosion etc.

In addition to pure polymer materials there has also been developed products based on materials that may be described as hybrids between inorganic and organic materials, which means that these materials are macro molecules that may have an inorganic core and organic branches.

Organic/inorganic hybrid polymers (HP) are prepared based on a SINTEFs well-defined technology (WO2005100450) corresponding to properties of hyperbranched polymers and are used e.g. as additives for polymer products like thermoset plastics and in lacquers and other types of coatings for surface protection. Used in appropriate amounts and with convenient particle size such hybrid polymers may contribute to a significant improvement of the properties of the plastic material or the lacquer, hereunder an increased wear resistance/scratch resistance and/or weather resistance.

It will be shown that the HP additives are suitable for a number of applications within organic chemistry and in particular within polymer chemistry and that they can provide a stabilizer for thermoplastics with a broader range of utility than that known, mono-functional stabilizers exhibit.
