Thermal behavior of the products of 2-chloro-2-propen-1-ol oligomerization

Abstract

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+.

Porous oligomeric materials synthesised using a new, highly active precatalyst based on ruthenium(iii) and 2-phenylpyridine

“…At 429.7 °C, the thermally cross-linked oligomer undergoes complete thermal decomposition. 41 For comparison, the oligomers presented in the literature are a kind of derivative of polyvinyl chloride (PVC), 42 the glass transition temperature of which ranges from 77 to 80 °C depending on the molecular weight. The exceptional difference is likely due to the oligomers described in the literature having much shorter oligomer chains than the polyvinyl chloride polymer.…”
