Airborne Isocyanates, Aminoisocyanates and Amines
, 2001 Isocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed

Polyurethane Foams From a Triblock Copolymer Polyol With CO2‐Derived, High‐Tg Polycarbonate Segments
Journal of Applied Polymer Science, EarlyView.Polyurethane foam (PUF) properties are tuned by incorporating polyol with 0–15 wt% CO2‐derived poly(cyclohexene carbonate) (PCHC) segments (Tg = 104°C). Network PUFs are synthesized using CO2‐derived triblock copolymer polyol with PCHC hard segments and a polycaprolactone soft segment.

Aerosols of Isocyanates, Amines and Anhydrides : Sampling and Analysis
, 2007 This thesis presents methods for air sampling and determination of isocyanates, amines, aminoisocyanates and anhydrides. These organic compounds are generated during thermal degradation of polymers such as polyurethane (PUR) or epoxy. Isocyanates, amines

American Journal of Industrial Medicine, 2015 Background Isocyanates remain a leading cause of work-related asthma (WRA). Methods Two independent data systems were analyzed for the period 1993–2008: (1) State-based WRA case surveillance data on persons with isocyanate-induced WRA from four states ...

Diol Chain‐Length Effects in Adipate and Succinate Polyesters for Thermoplastic Polyurethanes
Journal of Applied Polymer Science, EarlyView.This study examines 20 aliphatic polyesters as soft segments for thermoplastic polyurethanes (TPU), synthesized from adipic or succinic acid and diols (C2, C3, C4, C5, and C6). A pronounced odd‐even effect shows that even diols crystallize, while odd diols remain amorphous.

New methodology for specific inhalation challenges with occupational agents
Respiratory Research, 2010 Background Inhalation challenges are used for diagnosing occupational asthma (OA). The initial methodology consisted of a "realistic" exposure without monitoring nor controlling exposure.
