    摘要： A mineral-compatible cationic emulsion composition with polymer stabilizers, and methods for utilizing same in paving and other applications is disclosed. In one aspect, a bitumen-in-water emulsion composition includes at least one bitumen material, at least one polymer stabilizer, at least one emulsifier, and water, where the emulsifier is a cationic surfactant, an amphoteric surfactant, or a mixture of both, and the polymer stabilizer is a natural or synthetic cationic polymer consisting of alkylene polyamines, alkyl polyamines, polyquaternary polymers, polyvinylamine, polyvinylimidazoline, polyester polyquaternary polymers, polyether polyquaternary polymers, or mixtures thereof. The inclusion of polymer stabilizer in the cationic emulsion increases the stability of the emulsion and increases the compatibility of the cationic emulsion with negatively charged minerals.

    摘要： A process for rendering a polyamine-epihalohydrin resin storable stable, comprising: treating a composition containing a polyamine-epihalohydrin resin which includes CPD-forming species with at least one acidic agent, wherein the pH during treatment is about 1.1 or less; the time is for at least about 2 hours to at least about 24 hours, and the temperature is at least about 30 °C to at least about 90 °C, wherein the temperature range is combined with the time period range in an inverse relationship, to at least one of inhibit, reduce and remove the CPD-forming species to obtain a gelation storage stable reduced CPD-forming resin so that the composition containing the reduced CPD-forming polyamine-epihalohydrin resin, when stored at pH 1 for 24 hours at 50 °C and measured at 24 hours, produces less than about 500 ppm dry basis of CPD.
