Abstract (en)
[origin: WO9630446A1] Disclosed are oil-in-water asphalt emulsions comprising asphalt dispersed as the discontinuous phase in an aqueous continuous phase, the emulsions containing one or more anionic emulsifiers selected from the group consisting of compounds of the formulas (Ia), (Ib), (II), (III), (IVa) and (IVb): (R<1>CH(OH)-(CH2)mSO3)iX (Ia); (R<1>CH=CH(CH2)m-1SO3)iX (Ib); (R<2>O-(AlkO)cCH2COO)iX (II); ((R<3>)k-(A)-SO3)iX (III); wherein R<1>, R<2> and R<3> are C6-40 hydrocarbyl, m is 1-10, X is -H or a cation, c is 1-20, A is phenyl or polycyclic aromatic, k is 1-3, and i is the valence of X; and R<4>-(OC3H6)0-1-(C(O)NH(CH2)1-3)0-1-N(Z<1>)(Z<2>)0-1-ZCOOX (IVa); R<4>-(OC3H6)0-1(C(O)NH(CH2)1-3)0-1-N(Z<1>)(Z<2>)0-1-ZSO3XH (IVb); wherein R<4> is C4-24 alkyl or alkylene, f is 1-6, X is -H or a cation, Z is (CH2)f, CH2CHOHCH2, or CH2CH2OCH2CH2, and Z<1> and Z<2> are CfH2f+1 or CfH2fOH, or in (a) Z<1> can be -ZCOOX.
