Abstract:
1. A poly(ureaurethane) comprising a reaction product of components comprising: (1) a polyisocyanate functional urethane prepolymer which is the reaction product of components comprising: (2) at least one amine curing agent which reacts with isocyanate functional groups of the polyisocyanate functional urethane prepolymer to form a urea linkage, the amine curing agent being selected from the group consisting of: 4,4′-methylenebis(3-chloro-2,6-diethylaniline), 2,4-diamino-3,5-diethyl-toluene, 2,6-diamino-3,5-diethyl-toluene, dimethylthiotoluenediamine (DMTDA), 4,4′-methylene-bis-(2-chloroaniline), ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA), tetraethylenepentamine (TEPA), pentaethylenehexamine (PEHA), piperazine, morpholine, piperidine, diethylenediamine (DEDA), 2-amino-1-ethylpiperazine, C wherein R 3 and R 4 are each independently C 1 -C 3 alkyl, and R 5 is selected from hydrogen and halogen; wherein R 20 , R 21 , R 22 , and R 23 are each independently selected from H, C 1 -C 3 alkyl, CH 3 —S—and halogen, and mixtures thereof; wherein the reaction components comprise less than about 5 weight percent of polyester polyol, less than about 5 weight percent of polycarbonate polyol and less than about 5 weight percent of polyether polyol.
