Abstrakti

The present invention relates to the preparation of novel sulphur-containing polyamides from renewable sources, and methods for producing the same. The production method involves the preparation of sulphur-containing functional monomers, which can subsequently undergo polycondensa- tion to from either AB- or AABB-type sulphur-containing polyamides. Furthermore, these novel polyamides display superior water barrier/adsorption, better retention of physical properties at elevated temperature (≥Tg) and easier processability and polyolefin-compatibility than conventional polyamides. Potential applications for these novel polyamides include high-end electronic devices, organic light- emitting diode devices, components for charge-coupled devices (CCDs) and image sensors (CISs), films and coatings, food packaging films, furniture, appliances, sports equipment, consumer goods, wire and cable, and automotive components.
