    Synthesis of difunctional polystyrenes and their incorporation in block copolymers with bisphenol a polycarbonate (1969)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A-1: Polymer Chemistry 7 (1969), S. 1339-1347 
    Details
    ISSN: 0449-296X

    Topics: Chemistry and Pharmacology
    Notes: Block polymers of polystyrene and bisphenol A polycarbonate have been prepared and their bulk viscosities studied as functions of both shear stress and polystyrene block length. The polystyrene blocks were α,ω-diacid chlorides prepared from the reaction of “living” polystyrenes with diacid chlorides. These reactions were studied in order to discover the most effective way of preparing the polystyrene diacid chlorides. The polystyrene diacid chlorides are best prepared by reaction of disodiopolystyrene with phosgene. The flow properties of the block copolymers depend on the composition of the polymers but do not depend on the length of the polystyrene blocks.

    Chemistry of polybutadiene - iron carbonyl systems (1966)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A-1: Polymer Chemistry 4 (1966), S. 1509-1516 
    Details
    ISSN: 0449-296X
    Keywords: Physics ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The treatment of polybutadienes with iron carbonyls results in formation of polymers containing tricarbonyl(conjugated diene)iron units [C8H12Fe(CO)3] and also results in geometrical isomerization of free double bonds. Heating of the iron carbonyl-containing polymers gives ferromagnetic products with enhanced thermal stability. The incorporation of iron carbonyl groups into the polymer is favored by basic solvents and high temperatures, the geometrical isomerization by acidic solvents and low temperatures. Steric factors are powerful in determining the rate of isomerization.
