Title:
WATER-BORNE POLYAMIDE-UREA DISPERSIONS
Document Type and Number:
WIPO Patent Application WO/2014/126741
Kind Code:
A3
Abstract:
Polymers are disclosed that incorporate large portions of elastomeric polyamide oligomers connected with polyisocyanates. These polymers have enhanced properties over similar polyurethanes due to better hydrolysis resistance of polyamides over polyesters and better UV resistance of polyamides over polyethers. Polyurea linkages can also improve properties over polyurethane linkages. Composites and hybrids of these polymers and other polyamides with vinyl polymers are also disclosed and claimed.
