The main symptoms of allergic rhinitis (AR) are sneezing, rhinorrhea and nasal obstruction. In patients with AR, levels of nerve growth factor (NGF) and vascular endothelial growth factor (VEGF) increase. Olopatadine hydrochloride (olopatadine) is an anti-allergic agent with histamine H1 receptor antagonistic action.

Abstract Gelator 1 which has two aliphatic chains, three amide groups, and one glucosamine unit showed an excellent gelation ability for many organic solvents. The in situ cross-link of these organic gels by toluene-2,4-diisocyanate resulted in new robust gels with high Tgel values, retaining their gel fiber super-structure.

Abstract Water-resistant composite plastics were prepared from soy protein isolate (SPI) or soy dreg (SD), poly( ɛ -caprolactone) (PCL) and toluene-2,4-diisocyanate (TDI) as the compatibilizer by blending and one-step reactive extrusion (REX) followed by compression-molding.

Abstract Plastic materials that release free toluene-2,4-diisocyanate (TDI) can be commonly found in sports venues. As the presence of TDI in the atmosphere will result in severe air pollution, the WHO has enforced strict regulations to ensure that the proportion of the free TDI monomer in the isocyanate-polymer is lower than 0.5%.

Talanta, 2007
Ethyl parathion and toluene 2,4-diisocyanate (2,4-TDI) vapors were generated using a vapor generation system that was designed for the evaporation of liquid samples at known flow rates. The vapor generation of parathion and 2,4-TDI posed a challenge because of their low volatility and tendency to absorb into surfaces of the vapor generation system ...

A new type of polyurethane (PU) has been synthesized by using hydroxyl terminated liquid natural rubber (HTNR) and poly(e-caprolactone) (PCL) as a soft segment and toluene-2,4 diisocyanate (TDI) as a hard segment. This PU becomes a biodegradable and recyclable polymer. The PU samples were synthesized by solution polymerization.

AbstractFurther studies on the thermal degradation of POPG‐TDI polymer have been carried out. It has been shown that at temperatures of ∼200°C., the predominant degradation process involves random scission of the urethane linkages to give substantial amounts of isocyanate and hydroxyl.

Late asthmatic reaction (LAR) and dual asthmatic reaction (DAR) were developed in guinea pigs by repetitive treatment with toluene 2,4-diisocyanate (TDI). Development of LAR or DAR seemed to dependent on the TDI-treatment period. IgG was demonstrated in both the LAR and DAR models, whereas IgE was only in the DAR model. Increased numbers of eosinophils

Journal of Applied Polymer Science, 1998
Based on an expanded kinetic scheme for 32 subsequent and parallel reactions that yield linear polyurethane, a mathematical model was developed for a gradual polyaddition process involving toluene 2,4-diisocyanate and 1,4-butanediol. Unlike the earlier models, this one followed Flory's assumption and made the reactivities of the oligomers dependent ...
