Ahphatic esters such as adipates, azelates and sebacates enable PVC to remain flexible even in arctic climates. Di-octyl sebacate is especiaUy eflective in this respect, but expensive. Adipates are widely used in food packaging film because of their acceptability under food contact regulations. They have a low viscosity, making them convenient for PVC paste formulations. Examples include di-iso-nonyl adipate and benzyl octyl adipate. 

Desmocoll 176 is compatible with such plasticizers as benzyl butyl phthalate, diphenyl cresyl phosphate and trichlorethyl phosphate. It has slight or no compatibility with dibutyl phthalate, dioctyl phthalate, triphenyl phosphate, tricresyl phosphate, dibutyl adipate, benzyl octyl adipate, phenyl and cresyl alkyl sulphonates.

Commercially used plasticizers such as di n-octyl adipate, di -octyl sebacate, di(2-ethylhexyl)phthalate and butyl benzyl phthalate can contribute to the photo-dehydrochlorination of poly(vinyl chloride) and this is attributed to a free radical mechanism, whereby a radical is first formed in the plasticizer and then transferred to the polymer [255, 297, 298, 688, 1636, 2270]. In the case ofdi(2-ethylhexyl)phthalate and tri(2-ethylhexyl)trimellitate the observed effects are even more drastic under conditions of solar irradiation [554]. This effect has been attributed to the fact that the trimellitate exhibits a much greater absorption in the wavelength range of the solar spectrum and hence is more likely to form free radicals. 

Successful results have been obtained (Renfrew and Chaney, 1946) with ethyl formate methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec.-butyl and iso-amyl acetat ethyleneglycol diacetate ethyl monochloro- and trichloro-acetates methyl, n-propyl, n-octyl and n-dodecyl propionates ethyl butyrate n-butyl and n-amyl valerates ethyl laurate ethyl lactate ethyl acetoacetate diethyl carbonate dimethyl and diethyl oxalates diethyl malonate diethyl adipate di-n-butyl tartrate ethyl phenylacetate methyl and ethyl benzoates methyl and ethyl salicylates diethyl and di-n-butyl phthalates. The method fails for vinyl acetate, ieri.-butyl acetate, n-octadecyl propionate, ethyl and >i-butyl stearate, phenyl, benzyl- and guaicol-acetate, methyl and ethyl cinnamate, diethyl sulphate and ethyl p-aminobenzoate. 

Figures 10.45 and 10.46 show that the effect of plasticizer concentration increase cannot be described by a simple relationship. Some plasticizers (e.g., dioctyl azelate, dioctyl adipate, and dioctyl phthalate) increase stability of PVC composition when their concentrations increase and other plasticizers (e.g., benzyl butyl phthalate, dibutyl phthalate, diphenyl octyl phosphate, and tricre-syl phosphate) decrease stability of plastificate when their concentration increases. Both groups display linear relationships with good correlation coefficients. Comparing two...
