    Notes: A novel class of emulsions has been introduced. Emulsions of this class comprise two immiscible polymer solutions and a graft copolymer as an emulsifying agent. The name polymeric oil-in-oil emulsions (POO emulsions) has been suggested for the new emulsions. The concept has been verified with several systems of polymer solutions. The polymers used here are poly(ethyl acrylate), poly(methyl methacrylate), polystyrene, polyvinyltoluene, poly-p-tert-butylstyrene, and a styrene/acrylonitrile copolymer.

    Heterogeneous polymer systems. II. Mechanism of stabilization of polymeric oil-in-oil emulsions (1965)

    Notes: Polymeric oil-in-oil emulsions (POO-emulsions) are a new class of emulsions comprising two immiscible polymer solutions and a graft copolymer as an emulsifying agent. A mechanism of stabilization of POO-emulsions has been proposed which explains why graft copolymers act as POO-emulsifiers, why they accumulate in the interface of POO-emulsions, and why they provide coalescence barriers. The basic hypothesis is that the emulsifying graft copolymers accumulate in the interface as a result of the phenomenon of phase separation of polymers in solution, and that this phenomenon also provides the repulsive forces between colliding droplets which stabilize POO-emulsions. The formation of micelles of graft and block copolymers as a result of phase separation has been discussed, and a literature survey on the behavior of graft and block copolymers in solution has been included to support the proposed mechanism.

    Heterogeneous polymer systems. IV. Mechanism of rubber particle formation in rubber-modified vinyl polymers (1966)
    New York : Wiley-Blackwell

    Notes: A mechanism for the formation of rubber particles in the polymerization of solutions of rubber in vinyl monomers is presented. A polymeric oil-in-oil emulsion is formed in the first phase of the polymerization. This polymeric oil-in-oil emulsion is transtormed into a solid dispersion of rubber in vinyl polymer in the second phase of the polymerization. A phase inversion takes place in the emulsion in the first phase of the polymerization. Rubber solution droplets are formed at the phase inversion point. These droplets harden as the polymerization proceeds and are gradually transformed into the solid, crosslinked rubber particles of the final polymer.
