In-situ polymerization behaviour of bone cements

Journal of Materials Science: Materials in Medicine, 1997
The polymerization behaviour of bone cements during total hip replacements is characterized by a fast and highly non-isothermal bulk reaction. In the first part of this paper the reaction kinetics are analysed by calorimetric analysis in order to determine the rates of polymerization in isothermal and non-isothermal conditions.
