  • Patent number: 6540822
    Abstract: A method of emulsifying asphalt using a polyamine polybetaine, preferably a dibetaine, as an emulsifier or co-emulsifier and an emulsion of asphalt, water and a polybetaine, preferably a diamine dibetaine. The advantages of using a polyamine polybetaine as an emulsifier or co-emulsifier include its ability to provide superior cationic and anionic emulsions, and slow-setting emulsions at low use levels, and the excellent adhesion of the cured asphalt film.

  • Patent number: 5945393
    Abstract: Novel nonionic gemini surfactants are extremely effective emulsifiers for oil-in-water emulsions that provide improved detergency at even low concentration levels. The surfactants are characterized by the formula: ##STR1## wherein R.sub.1 is independently H or a C.sub.1 to C.sub.22 alkyl, R.sub.2 is C.sub.6 to C.sub.22 alkyl and R.sub.3 is D.sub.1 --R.sub.4 --D.sub.1 or R.sub.4 --D.sub.1 --R.sub.4 wherein R.sub.4 is independently a C.sub.1 -C.sub.10 alkyl group, --O--R.sub.5 --O--, or aryl, e.g. phenyl, and D.sub.1 is independently --O--, an amide group ?--C(O)N(R.sub.6)--!, an amino group ?--N(R.sub.6)--!, --O--R.sub.5 --O--, or aryl. (EO).sub.a (PO).sub.b is a polyether group and Z is a C.sub.1 -C.sub.4 alkyl, or an alkylaryl or hydrogen wherein EO represents ethyleneoxy radicals, PO represents propyleneoxy radicals, a and b are numbers of from 0 to 100, a is preferably from about 0 to about 30 and b is preferably from about 0 to 10, wherein a plus b is at least one, and the EO and PO alkyl or alkylaryl.
