脲基甲酸酯

嵌段共聚物令人满意的拉伸强度归于过量的TDI所形成的脲基甲酸酯交联键。

The satisfactory tensile strength of block copolymers may be attributed to the formation of allophanate crosslinks by the introduction of excess TDI .

通过调整配方和工艺，由脲基甲酸酯直接合成法降低预聚物中游离TDI的含量。

The content of free-TDI in prepolymer is lowered by directly synthesizing allophanate based on the adjusted formulation and process .
