Nine derivatives of nitrophthalic acids and nitrophenols were synthesized as potential plasticizers for polymers and structurally characterized by H-1 NMR and elemental analysis. The time dependences of the weight loss for the nitro derivatives synthesized and for commercial plasticizers (dibutyl phthalate and dioctyl phthalate) were obtained by gravimetric method at 100AC, and their volatilities and dipole moments were calculated. The resultant nitroplasticizers are considerably less volatile than dibutyl phthalate. Low volatility is associated not so much with high molecular weight as with high polarity. The nitroplasticizers are well compatible with cellulose esters and exhibit low rates of migration from polymer films.

The present invention provides an immunoassay for phthalic acid esters, which comprises measuring the phthalic acid esters contained in a sample using an antibody produced with a conjugate of a carrier protein and a phthalic acid ester derivative represented by the formula
wherein R1 and R2 may be the same or different and are hydrogen, alkyl, cycloalkyl or phenylalkyl, with the proviso that both of R1 and R2 are not hydrogen; m is an integer from 1 to 5; and Y is amino or carboxyl.
