THE VISOELASTIC PROPERTIES OF A ZINC PHOSPHINATE POLYMER.

Abstract

The viscoelastic behaviour of an inorganic glass, the co-ordination polymer Zn(OP(Ph)(Me)0)2, was investigated by a ball-indentation method. The polymer was found to exhibit the properties of a Maxwell body. The temperature dependence of the melt viscosity is of the Arrhenius form over the temperature range considered, giving an apparent activation energy of 74 kcal/mole for viscous flow, but does not agree with that predicted by the WLF equation in its usual form. From considerations of its intrinsic viscosity in benzene and its viscoelastic behaviour, it is concluded that the polymer is of low molecular weight.
