Synthesis and trans-ureation of N,N '-diphenyl-4, 4 '-methylenediphenylene biscarbamate with diamines: a non-isocyanate route (NIR) to polyureas [PDF]

, 2014
A non-isocyanate route (NIR) of making polyureas of high molecular weight has been found through transureation of N,N'-diphenyl-4,4'-methylenediphenylene biscarbamate (4,4'-DP-MDC) with a variety of diamines and mixed diamines. The preparation of 4,4'-DP-

Biomodeling Remote Consequences of Acute Phenylcarbamate Poisoning

Journal Biomed
Acute intoxications with pesticides, herbicides, and insecticides based on cholinesterase inhibitors account for up to 50% of hospitalizations due to toxic poisoning, leading to either long-term incapacitation or disability. These compounds predominantly cause dysfunction of the cholinergic mediator system, while exhibiting non-receptor effects.
