| 摘要 |
The present invention relates to a highly branched polyamide oligomer of general formula (1) as defined in the description, to the process for preparing such branched oligomers and to different uses thereof. As well kno wn to the man skilled in the art, the implementations and efficacy of the different polyamide oligomers may vary, depending on their structure and valency (reactive groups composition). Polyamide oligomers may be used, for example, as epoxy hardeners in the preparation of thermosetting compositions , as thermoplastic hot melt adhesives, as adhesion promoters and many other suitable applications. The highly branched oligomers disclosed have been sho wn to be highly efficient, for example, as epoxy hardeners, inter alia, in the formation of glue, lacquer, enamel or sealant mixtures.
