摘要:
Novel meta phenylenediamines are provided having one or two particular benzyl radicals as substituents along with other optional substituents on the aromatic diamine ring and optionally substituents on the benzyl aromatic ring.The diamines are sterically hindered and thereby have lower amine reactivity as compared with the unsubstituted diamines.The diamines are useful as curing agents for epoxy resins and find particular utility as extenders in the formation of novel polyurethane-polyurea polymers.

摘要:
A diagnostic composition containing as a chromogen a diamino-biphenyl derivative in which at least one of the hydrogen atoms in the amino groups thereof is replaced by a lower alkyl group by reaction with an alkylating agent. The diagnosing instrument is prepared by impregnating a bibulous, porous support in a solution comprising the diagnostic composition and optionally a saccharide oxidase, peroxidase and a guaiac, and, if necessary, a buffer, a surfactant, a background adjusting dye and/or an agent for increasing the viscosity of the composition. This diagnosing instrument can be handled in a simple and convenient way and is used to identify semi-quantitatively a saccharide in body fluids or excrements of humans or animals with reliability.
