    Polymer conformation and viscometric behaviour:1. conformational transition in poly (benzyl methacrylate) in dilute solutions
    (1983) Gargallo Gómez, Ligia Teresita; Muñoz, M. I.; Radić Foschino, Deodato D.
    The viscometric and refractometric behaviour of poly (benzyl methacrylate) (PBM) in isobutyl methyl ketone (IMK) as a function of the temperature was studied. The viscometric relations in IMK and toluene by membrane osmometry and GPC at 25ºC were established. The viscometric results show discontinuities in the intrinsic viscosity [?] in IMK and sharp changes in the conformational and thermodynamic parameters K? and B. The variation on the unperturbed dimensions of the polymer chain was attributed to a conformational transition. The influence of the side groups was analyzed. The conformational behaviour of this polymer was compared with the saturated corresponding poly (cyclohexyl methyl methacrylate).

    Thermal degradation of chalcogenides containing poly(methacrylates)
    (1990) Muñoz, M. I.; Tagle Domínguez, Luis Hernán; Gargallo Gómez, Ligia Teresita; Radić Foschino, Deodato D.; Muñoz, M. I.; Tagle Domínguez, Luis Hernán; Gargallo Gómez, Ligia Teresita; Radić Foschino, Deodato D.
    Thermogravimetric analysis of aromatic poly(methacrylates) containing heterocyclic side chains were carried out. The effect of the substituent introduced into the side chain on the thermal stability of the polymer was investigated. The kinetic parameters of thermal degradation process were analysed. Different thermogravimetric profiles were obtained depending on the structure of the side chain of the polymer.
