Serum Specific IgG to Cytokeratin : A Useful Serologic Marker for Toluene Diisocyanate-Induced Asthma
… enough for the diagnosis of patients with toluene diisocyanate (TDI)-induced asthma. We evaluate the clinical significance of specific IgG to three major epithelial cytokeratins (CK)-CK8, CK18, and CK19-in 66 patients with TDI-induced asthma (group Ⅰ), compared with three control groups: …

The Prevalence and Clinical Significance of Newly Sensitization to Inhalant Allergens in Toluene Diisocyanate-induced Asthmatic Patients
BACKGROUND: It has been reported that half of toluene diisocyanate (TDI)-induced asthma patients had persistent asthmatic symptoms even after complete avoidance. We hypothesized that new sensitization to common inhalant allergens may contribute to persistent and aggravation of asthmatic symptoms. …

Synthesis and characterization of lignin-carbohydrate block copolymers
… is prevented. • Reaction of this block with 2,4 toluene diisocyanate (TDI) to form an isocyanate-capped CTA prepolymer under conditions that chain extension is limited and a sufficient NCO equivalent/mole is achieved (ie: 1 or 2). • Reaction in solution of this low DP CTA prepolymer with the HPL …

A study of the thermal degradation of flexible tdi-based polyurethane foams
… therefore, to study the degradation behaviour of toluene diisocyanate (TDI)-based polyurethane foams in order to determine the mechanisms which occur and the effect that various fire retardants have on the degradation mechanisms. The results have demonstrated that the degradation of TDI-based …

Structural and viscoelastic studies of flexible polyurethane foams
… main focus. A series of molded foams based on toluene diisocyanate (TDI) and glycerol initiated polyethylene-oxide-capped propylene-oxide was studied in terms of the structure property features. The results were in many instances compared to those obtained on conventional slabstock foams based …

Structure-Property Relationships of Flexible Polyurethane Foams
… polyols, or "monols", with water-extended toluene diisocyanate (TDI) based hard segments. The formulations of the monol materials were maintained similar to those of flexible polyurethane foams with the exceptions that the conventional polyol was substituted by an oligomeric monofunctional …

Smart Surfaces in Biobased Materials
… F-containing alcohol to the CP segment via toluene diisocyanate. Solutions containing F-terminated CP-segments showed typical critical micelle behavior. The critical micelle concentration depended on the molecular weight of the CP segment and the type of F-containing endgroup. The micelles …
