  • Patent number: 7067586
    Abstract: Block copolymers are prepared by living-type or semi-living type free radical polymerization, with said copolymers having at least one random block comprised of at least one hydrophobic monomer and at least one hydrophilic monomer. The selection of hydrophobic and hydrophilic monomers in the random block is determined by the relative hydrophobicity of the monomers to impart selected solubility or dispersability in water and/or alcohols of the overall block copolymer.

  • Patent number: 6890522
    Abstract: Cosmetic or personal care compositions, such as for styling hair, comprise a thermoplastic elastomer which is a block copolymer comprising a core polymer having a backbone comprising at least a proportion of C—C bonds and two or more flanking polymers. Each flanking polymer is covalently bound to an end of the core polymer and the core polymer and/or at least one of the flanking polymers is a copolymer derived from two or more monomers. The compositions comprise a cosmetically acceptable diluent or carrier.
