Polyoxyalkylene diamine reaction products which contain as the principle reaction component, a diamine having the formula: ##STR1## wherein R' independently represents hydrogen or methyl and x is a number having an average value of at least 1 to about 60 and a diisocyanate of the formula: ##STR2## The products of the invention are obtained by reacting an excess of polyoxyalkylene diamine with a diisocyanate in the presence of a polar solvent and have the following general structures: ##STR3## where B is alkyl group from diisocyanates, and R' has the same meaning as above. These products are further used to prepare coatings with improved properties by reacting said amine products with isocyanates prepolymers and epoxy material.
聚氧烷基二胺反应产物,其主要反应组分为具有以下式子的二胺:##STR1## 其中R'独立表示氢或甲基,x是平均值至少为1至约60的数字,以及具有以下式子的二
异氰酸酯:##STR2## 本发明的产物是通过在极性溶剂存在下将过量的聚氧烷基二胺与二
