1. A polymeric composition of matter having the formula
ApA′

  • 1-p[BCD]nZqZ′

    1-q wherein B is a polymer block, C is a polymer block that may be the same as or different from B, and D is a polymer block that may be the same as one of or different from both of B and C, n is a number from 5 through 105, A is a surface active endgroup, A′

    is a surface-modifying amphipathic moiety different from A, Z is a surface-modifying amphipathic moiety that may be the same as one of or different from both of A and A′

    , and Z′

    is a surface active endgroup that is different from Z but may be the same as one of or different from both of A and A′

    , with the proviso that at least one of A′ and

    Z is other than an alkylene ether-terminated poly(alkylene oxide), and p and q may be the same or different and each is a number from 0 through 1, wherein said polymeric composition of matter has a weight average molecular weight in the range 5000-5,000,000 daltons.
