Enthalpy relaxation of low molecular weight amorphous styrene oligomers measured with an adiabatic calorimeter

The thermal stability of the oligomers obtained by using 2-chloro-2-propen-1-ol as the monomer has been studied. The oligomers were synthesized using chromium(III) and oxovanadium(IV) complexes as the catalysts after activation by modified methylaluminoxane (MMAO-12). The complexes used as the catalysts were polycarboxylate complex compounds of oxovanadium(IV) and chromium(III). The studies have been conducted by two methods: thermal gravimetry and differential scanning calorimetry. The obtained results allow to determine the glass transition temperatures and thermal stability of the oligomers depending on the central catalyst cation Cr3+ and V4+.
