Sequence-block copolymers have well-controlled and precise monomer sequence. A highly ordered fluoro-containing block copolymer material can be prepared based on the sequence-block copolymer, which shows excellent patterning capability.

Polyurethane-based and epoxy-based coating compositions are described that provide coatings and adhesives that are clear, amphiphobic and durable. Both water and hexadecane readily slide off these surfaces without leaving a residue. Coatings with thicknesses ranging from about 10 nm to about 10 μm exhibited excellent transmittance properties. Such films exhibited durability against abrasion, ink-resistance, anti-graffiti, anti-fingerprint, and strong adhesion to glass surfaces. The coatings are applicable to electronic devices, fabrics, glass, etc. to prepare optically clear, stain-resistant, and smudge-resistant surfaces.

The present invention relates to a process for preparing a dispersion (D°), comprising: (E1) a polymerization performed M in an aqueous medium in the presence of: ° at least a pre-polymer (pO) of formula (R.sup.11)X—Z.sup.11—C(═S)—Z.sup.12-[A]-R.sup.12, which is soluble in the aqueous medium ° at least one free-radical polymerization initiator; and ° at least one ethylenically unsaturated hydrophobic monomer (m) with a ratio m/pO of the mass of the monomers (m) to the quantity of pre-polymer (pO) preferably below 10 000 g/mol whereby a dispersion of copolymers is obtained, including polymers with a living character; (E2) a conversion of the terminal groups of the copolymers that deprive the copolymers of their living character. The invention also relates to the use of dispersion (D°) for forming dispersions of hydrophobic polymers (Dp), suitable e.g. in fabric conditioning compositions.
