Two novel phosphorus-containing copolyesters were synthesized by direct polycondensation reaction of phenyl dichlorophosphate, 1,4-succinic acid and 1,4-butanediol using stannous chloride (SnCl2) and 4-Methylbenzenesulfonic acid as catalyst, and its chemical structures were identified by 1H and 31P nuclear magnetic resonances (1H

An improved method for assaying carbamylated acetylcholinesterase is described which has substantial benefits over current methods. Acetylcholinesterase was carbamylated with neostigmine and diluted extensively into buffer to allow decarbamylation to occur. At various times, phenyldichlorophosphate was added to the mixture
