Abstract
Compounds of the formula: <FORM:0953462/C2/1> wherein R1 and R2 are independently H or CH3 and R3 is a saturated branched C10-16 aliphatic hydrocarbon radical with a maximum of 11 C atoms in the longest chain may be prepared by adding a 10 to 50 mol per cent excess of an alcohol R3OH to cyclic butadiene sulphone (or the appropriate homologue) in the presence of 0.1 to 3 wt. per cent NaOH at 30 to 80 DEG C. Specified alcohols are commercial isodecyl (R3= a mixture of dimethyloctyl and trimethyl heptyl), isotridecyl (R3 = trimethyldecyl and tetramethylnonyl), and isohexadecyl (dimethylbutyl dimethylhexyl hydroxymethyl methane). The compounds are plasticizers for polyvinyl chloride (see Division C3).ALSO:Compounds of the formula: <FORM:0953462/C3/1> are plasticizers for polyvinyl chloride. R1 and R2 are independently H or CH3 and R3 is a saturated branched C10-16 aliphatic hydrocarbon radical with a maximum of 11C atoms in the longest chain. They may be prepared by adding a 10 to 50% mol. excess of an alcohol R3OH to cyclic butadiene sulphone (or the appropriate homologue) in the presence of 0.1 to 3% wt. NaOH at 30 to 80 DEG C. The excess alcohol improves the rate rather than the yield of the reaction. Specified alcohols are commercial isodecyl, isotridecyl and isohexadecyl which are mixtures of branched isomers. Specified optional ingredients for polyvinyl chloride compositions containing the plasticizers are unidentified secondary plasticizers, phosphites and cadmium-barium stabilizers and 2,6 di-t-butyl catechol.
