Abstract: The pot life of an isocyanate formulation is controlled by including a chain extender having (a) at least two secondary amine groups, (b) no primary amine groups, and (c) a reactivity low enough that the chain extender will not react sufficiently with isocyanate groups present in the isocyanate formulation to increase the viscosity of the isocyanate formulation to more than 2000 mPa·s within 5 seconds in the isocyanate formulation.

Abstract: This invention relates to an improved process for the production of tolyltriazole in which the tolyltriazole is a lighter colored product. The color improvement in the tolyltriazole produced from this process occurs when the ortho-toluenediamine reactant is previously stabilized by treatment with a compound selected from the group consisting of aldehydes, ketones, acetals and ketals. The process of the present invention reduces the need to purify (by, for example, filtration or distillation) the tolyltriazole prior to being used commercially.
