This invention relates to po!yurethane/polyureas. These poiyureihane/po!yurea materials comprise the reaction product of (A) a poiyisocyanate prepolymer having an NCO group content of about 4 to about 30% and an average functionality of 1.8 to 6, and (B) an isocyanate- reactive component comprising at least one aromatic diamine compound, The (A) poiyisocyanate prepoiymers herein comprise the reaction product of (1) at least one {cyclo)aliphalic poiyisocyanate with (2) an organic compound having 1,8 to 5 hydroxy! groups and a hydroxy! equivalent weight of 150 to 2000 g/eq., and which is selected from the group consisting of OH- functional poiybutadienes, OH-funcfional polyalkylene, OH-functional polyalkylene phthalates, OH-functional polyalkylene isophthalates, OH- functional polyalkylene terephthaiates and mixtures thereof. 本发明涉及聚氨酯/聚脲。这些聚氨酯/聚脲材料包含以下物质的反应产物：(A)多异氰酸酯预聚物，其具有的NCO基团含量为约4％至约30％且平均官能度为1.8至6，和(B)包含至少种芳族二胺化合物的异氰酸酯反应性组分。本文中的(A)多异氰酸酯预聚物包含以下物质的反应产物：(1)至少种(环)脂族多异氰酸酯与(2)具有1.8至5个羟基和150至2000克/当量的羟基当量重量的有机化合
