| Abstract: | Abstract： The methoxypolyethylene glycols （MPEG） were employed to modify aliphatic polyisocyanates. The influences of the molecular weight and amount of MPEG and different synthesis processes on the content of isocyanate （NCO） groups, viscosity, water dispersibility of the resultant modified polyisocyanates and the properties of two-component waterborne polyurethane coatings were investigated. The water dispersible polyisocyanates bearing urethane groups and those containing allophanate groups were compared. |
