Thermal degradation prior to ionization can cause decarbonylation or decarboxylation of the analyte. Decarbonylation, is observed for a-ketocarboxylic acids and a-ketocarboxylic acid esters, while decarboxylation is typical for p-oxo-carboxylic acids such as malonic acid and its derivatives and di-, tri-, or polycar-boxylic acids.

Typical thermal stabilizers for PVC are organic metal salts and soaps, phosphite, esters, and epoxy compounds. Examples are barium/zinc carboxylates [46], barium/cadmium carboxy-lates [47], calcium/zinc stearate [48], lead stearate [49],organotinmercaptides[50],organotin sulfides, organotin carboxylates[51], among others. Costabilizers such as 1,3-diketones, dihydropyridines, epoxy plasticizers, P-ketocarboxylic acid esters, phenolic antioxidants, a-phenylindols, and phosphates are used to improve the stabilizer s elfectiveness.
