    Notes: Heating of the sodium salts of chlorocarboxylic acids leads to exothermic elimination of sodium chloride and oligomerization of the organic backbone of the molecule. Thermochemical data of sodium 2-chloropropionate (1), sodium 3-chloropropionate (2) and sodium 2-chlorobutyrate (3) were derived. The reaction products were characterized by IR and NMR spectroscopy, and the degree of polymerization was determined by gel permeation chromatography (GPC).

    Silver Chloroacetate: Crystal Structure and Thermal Polymerization Mechanism (1997)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 130 (1997), S. 291-294

    Notes: The structure of silver chloroacetate was determined by single-crystal X-ray structure analysis. This represents the first salt of a monohalogenoacetic acid with a monovalent metal whose structure was determined with high precision. The salt undergoes a thermally induced solid-state polymerization to polyglycolide under elimination of silver chloride. A probable mechanism for a structure-determined reaction in the solid state is discussed.

    The Thermally Induced Solid-State Polymerization Reaction in HalogenoacetatesDedicated to Prof. Günther Klar on the occasion of his 60th birthday. (1996)

    Notes: Nine salts of halogenoacetic acids MOOC-CH2—X were prepared and characterized by their thermochemical reactivity. It was found that in seven cases elimination of MX led to polymerization of the organic part of the molecule. The resulting polyester, polyglycolide, could be isolated easily by washing the reaction product with water. It has a distinct porous morphology. The reaction takes place at moderate temperatures (100—200°C).
