ABSTRACT:
Star/comb-branched polyamides having good resistance to degradation upon exposure to shear are prepared by reacting polyvalent core compounds such as tribromoneopentyl alcohol with an oxazoline such as 2-ethyl-2-oxazoline to provide the desired polyamide. The polyamides are readily hydrolyzed with acid such as hydrochloric acid to form star/comb-branched polyamines. The polyamides and the polyamines are useful as viscosity enhancing agents in such applications as paints, mobility control agents and hydraulic fluids.
