应用

1,4-苯二异氰酸酯（PPDI）可用作：
  • 一种通过与烷基叠氮在吡啶中的交叉加成聚合反应合成高产聚合物的反应物。
  • 一种制备含金刚烷基的二脲和硫脲衍生物的有机构建块，可作为强效哺乳动物和人类可溶性环氧化物水解酶抑制剂。
  • 一种以二月桂酸二丁基锡（DBTDL）为催化剂合成聚乙二醇（PEG）/二氧化硅复合材料的偶联剂。

它也可用于：
  • 作为交联剂，研究硅烷化表面固定化酶的机理。
  • 在偶极双脲受体的合成中，这是一种硫酸氢的选择性受体。
  • 在聚脲抗蚀膜的沉积中，通过分子层沉积。

Poly(lactic acid) (PLA)/thermoplastic polyurethane (TPU) blends were melt-mixed and compatibilized to investigate their biocompatibility, biodegradability and thermally induced shape memory properties. The blend compositions were PLA/TPU: 80/20 (20TPU) and PLA/TPU: 50/50 (50TPU). 1,4-phenylene diisocyanate (PDI) was used in order to

We investigated the mechanism of enzyme immobilization on silanized surfaces through coupling agents (cross-linkers) in order to understand the role of these molecules on interfacial processes and their effect on catalytic activity. To this end, we used a model multimeric
