MORPHOLOGY CONTROL IN POLYMERIC MULTIPHASE SYSTEMS WITH BLOCK-COPOLYMERS AND STRUCTURED LATEXES

Some application possibilities of block copolymers for the morphology control in polymeric multiphase systems are reviewed. The microdomain formation of block copolymers in the solid state is illustrated in the case of functionalized block copolymers and for interpolymer complexe s. The preparation of ''hairy latex'' by emulsion polymerization in th e presence of hydrophilic-hydrophobic block copolymers is shown in con nection with their applications in the controlled agglomeration proces s of latexes and for the preparation of polymer particles having micro voids. The surface activity of block copolymers in polymeric oil-in-oi l systems is illustrated for silicone oil filled polymers. These mater ials have a low kinetic friction coefficient and act as reservoir syst ems with the lubricant incorporated in the polymer matrix.
