ABSTRACT:
A water dispersible, modified polyurethane which is the reaction product of polyisocyanate, polyether polyol, modifying agent containing at least one pendant hydrophobic group and at least two active hydrogen moieties and capping agent. The modified polyurethane may also include a second type of modifying agent which does not have a pendant hydrophobic group. The modified polyurethane can be prepared by reacting the polyisocyanate and the polyether polyol and then adding the capping agent and finally the modifying agent with or without the second modifying agent. The modified polyurethane resists microbial attack, exhibits superior efficiency in thickening aqueous compositions under high shear conditions and achieves acceptable sag and leveling.
