“…The composition of these esters is shown in Table IV under hydrocarboxylated samples (Nos. [17][18][19][20][21][22][23]. The main products characterized by mass spectrometry were 1,3-and 1,4-dicarboalkoxy esters relative to each other from hydrocarboxylation of methyl linoleate and tricarboalkoxy esters from methyl linolenate (16).…”

Methyl mono‐, di‐, and tricarboxystearates were prepared by either a two‐step hydroformylation‐oxidation reaction or direct hydrocarboxylation of unsaturated vegetable oil methyl esters. Procedures were developed for preparing alkyl dicarbomethoxy‐, dicarboethoxy‐, and dicarbobutoxystearates. These triesters, along with some di‐ and tetraesters from mono‐ and tricarboxystearic acids, were evaluated as primary plasticizers for polyvinyl chloride (PVC). Except for butyl carbobutoxystearate, the esters were compatible at the 32% level and had properties equal or superior to those of dioctyl phthalate. Methyl and butyl diesters of carboxystearic acid had undesirable migration and volatility properties. The migration and volatility properties of some tri‐ and tetraalkyl esters were equal to or better than the controls. Of the various esters tested, methyl dicarbomethoxystearate containing 13–49% methyl tricarbomethoxystearate was an efficient plasticizer for PVC at the 32% level.

“…When changes in sample surface upon heating prevented spectrophotometric measurement of heat stability, the test films were evaluated visually and compared by color with films whose heat stabilities could be measured directly. Compatibility numbers were calculated in keeping with the empirical relationship noted by Riser and Palm (16).…”

“…One of the authors (G.R. Riser) earlier suggested that the compatibility number is useful in characterizing monomerle ester plasticizers (16). Figure 1 compares oligomeric esters from brassylic acid and mixed crambe dicarboxylic acids ("crambate") with monomeric and polymeric esters in terms of compatibility number.…”

Seventeen oligomeric plasticizers were prepared by polyesterification of long chain dicarboxylic acids with propylene glycol and terminator acid or alcohol. All, except one terminated by dodecyl alcohol, were compatible with poly(vinyl chloride). Films plasticizied with these polyesters were similar in transparency and flexibility to films plasticized with bis(2ethylhexyl) phthalate. Poly(vinyl chloride)sheets containing brassylic acid polyesters with Mn of 2200-2300 or a crambe mixed dicarboxylic acids polyester with Mn of 2100 exhibited superior permanence with overall performance comparable to sheets plasticized with bis(2-ethylhexyl) phthalate commercial polymeric plasticizer.
