Thermoplastic Urethane Chemical Crosslinking Effects

Journal of Elastomers & Plastics, 1975
AbstractThis paper reviews the chemical structures and attendant polymer morphology that have been advanced to explain the virtual crosslink (VC) phenomenon in segmented polyurethane elastomers. The different chemical methods employed to produce useful vulcanizates from the classical polyurethane elastomer use‐forms (castable liquid, millable gum ...

Cardiovascular Effects of Environmental Chemicals

Otolaryngology–Head and Neck Surgery, 1996
This article presents recent data on several environmental toxins: lead, carbon disulfide, asbestos, arsenic, ozone, cadmium, vinyl chloride, fiuorocarbons, freon, and pesticides. These environmental toxins produce both hypertension and cardiac arrhythmias in most studies, and they are not necessarily related to primary lung disease and secondary heart
