Abstract: A process for the production of a thermoplastic elastomer containing hard segments (a) of a polyester and soft segments (b) containing repeating units derived from an aliphatic carbonate, in which process a precursor thermoplastic elastomer is subjected to solid state post condensation at a temperature between 140 and 170° C. Also claimed is the thermoplastic elastomer.

Abstract: Processes for making a fluid conduits and fluid conduits made thereby are disclosed. The fluid conduits include a mono-layer formed of at least 80 wt %, based on total weight of the mono-layer, of a thermoplastic elastomer in an amount of at least 80 wt % with respect to the total weight of the mono-layer. The thermoplastic elastomer is preferably a block copolymer elastomer formed of hard segments (e.g., polyesters, polyamides and/or polyurethanes) and soft segments (e.g., aliphatic polyethers, aliphatic polyesters and/or aliphatic polycarbonates) and exhibits a melt flow rate measured at 230° C. under a load of 10 kg (MFR 230° C./10 kg), according to ISO1133 (2011) of at most 40 g/10 min and having a heat resistance of at least 250 hours at 175° C. at which the elongation at break remains at least 100% as measured according to ISO 527 with a test speed of 50 mm/min.

Abstract: A thermoplastic elastomer contains (a) hard segments of a polyester and (b) soft segments containing repeating units derived from an aliphatic carbonate, wherein the thermoplastic elastomer exhibits a melt flow index (MFI) measured at 230° C. under a load of 10 kg (MFI 230° C./10 kg) according to ISO1133 (2011) of at most 40 g/10 min. The thermoplastic elastomer is produced by subjecting a precursor of the thermoplastic elastomer to solid state post reaction processing at a temperature between 140 and 170° C. until the thermoplastic elastomer has the required MFI of at most 40 g/10 min measured at 230° C. under a load of 10 kg (MFI 230° C./10 kg) according to ISO1133 (2011).
