Definitions
- the present invention relates to a process for the preparation of metal nanoparticles. Preference is given to a process for the production of polyol and metal nanoparticle-containing (intermediate) products which are suitable directly for further processing in polyurethane products, in particular in polyurethane-based sealants and adhesives.
- WO2007 / 004767 describes silicone-based sealants which contain nanosilver particles as antibacterial and fungicidal additive.
- Silver nanoparticles can also be produced in polyethylene glycol (400 Da) by reduction with hydrogen gas at room temperature [Wenjin Yan, Rui Wang, Zhaoqing Xu, Jiangke Xu, Li Lin, Zhiqiang Shen, Yieng Zhou, Journal of Molecular Catalysis A. Chemical 2006, 255, 81-85].

- Also should be preferred contain as few "extraneous" additives that can adversely affect the properties of the polyurethane products.
- Polyvinylpyrrolidone retains or attracts water due to its hydrophilic properties. The presence of water is very troublesome in the further processing of the polyols with isocyanates to polyurethane products due to pertinent side reactions. Polyvinylpyridine can also lead to undesired reactions with Lewis acid catalysts from polyurethane synthesis. Hydroxy-functional compounds such as ascorbic acid or starch are reactive towards isocyanate groups, which leads to undesirable side reactions with isocyanates. Substances such as starch or polyvinyl pyrrolidone tend to form hydrogen bonds. The formation of hydrogen bonds in, for example, for further processing to sealant certain PU prepolymers generally leads to an increase in viscosity, which adversely affects the further processing, (formulation). This should be avoided as much as possible in adhesives and sealants.

- Comparative Example V-2 Batch method
- only very coarse particles were observed (by eye), with a high proportion in a particle size significantly greater than 1 mm. It could be shown that very small nanoparticles can be obtained by the spinning disc method and by using high molecular weight polyols.
- batch processes and the use of low molecular weight polyols lead to an unsatisfactory result.
- the relative conversion of the reduction reaction to silver for the three samples B-1, B-2 and V-1 was approximately determined by DLS measurements.
