The construction, operation and performance of a twin-cell differential calorimeter is described. The calorimeter was constructed primarily to detect the changes of enthalpy resulting from specific interactions between polymers in solution and monomers and thus to identify systems in which the monomer is likely to polymerize at an enhanced rate on the polymeric 'template'. It is shown that with this calorimeter it is also possible to measure the heats of mixing at high dilution of liquids of low molecular weight with fair accuracy. The heats of mixing so obtained for several pairs of liquids agree well with values given in the literature.
