Application

1,4-Phenylene diisocyanate (PPDI) can be used as:
  • A reactant to synthesize high yield polymers via criss-cross addition polymerization reaction with alkyl aldazines in pyridine.
  • An organic building block to prepare adamantyl-containing diurea and thiourea derivatives applicable as potent mammalian and human soluble epoxide hydrolase inhibitors.
  • A coupling agent to synthesize polyethylene glycol (PEG)/silica composite material using dibutyltin dilaurate (DBTDL) as a catalyst.

It can also be used:
  • As a cross-linking reagent to investigate the mechanism of enzyme immobilization on silanized surfaces.
  • In the synthesis of the dipodal bis-urea receptor, a selective receptor for hydrogen sulfate.
  • In the deposition of polyurea resists films via molecular layer deposition.

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
