AB  - The thermal decomposition kinetics of solid Zinc(II) bis(dialkyldithiocarbamate) complexes, Zn (S<SUB>2</SUB>CNR<SUB>2</SUB>)<SUB>2</SUB>, where R= i-C<SUB>3</SUB>H<SUB>7</SUB>, n-C<SUB>4</SUB>H<SUB>9</SUB>, i-C<SUB>4</SUB>H<SUB>9</SUB> and n-C<SUB>5</SUB>H<SUB>11</SUB>, were studied by using isothermal thermogravimetric heating  technique.  Results  show  that  the  thermal  decomposition of these complexes  occurs in a homogeneous  liquid  phase,  after  melting,  according  to  a   unidimensional   phase-boundary   reactions model, R<SUB>1</SUB>. The thermal stability was found to be in the following order: Zn(S<SUB>2</SUB>CNBu<SUP>i</SUP><SUB>2</SUB>)<SUB>2</SUB>< Zn(S<SUB>2</SUB>CNPr<SUP>i</SUP><SUB>2</SUB>)<SUB>2</SUB><  Zn(S<SUB>2</SUB>CNBu<SUP>n</SUP><SUB>2</SUB>)<SUB>2</SUB>< Zn(S<SUB>2</SUB>CNPe<SUP>n</SUP><SUB>2</SUB>)<SUB>2</SUB>.
