Monoesters derived from a dihydric alcohol and a carboxylic acid such as benzoic acid are secondary plasticizers for non-aqueous and solventless plastisols containing primary plasticizers that do not contain unreacted alkanol groups.

Plasticizer compositions for non-aqueous plastisols

Mixtures of esters produced by reacting a mixture of aromatic and aliphatic monocarboxylic acids with a diol containing from 2 to 12 carbon atoms are effective plasticizers for plastisols containing dispersion grade polymers of vinyl chloride. The freezing point of the present ester mixtures and their efficacy as plasticizers can be varied by adjusting the type and relative concentration of the aliphatic acid used to prepare the plasticizer. The ester mixtures can also be used as plasticizers for other organic polymers.

Plastisol compositions comprising vinyl chloride polymers and mixtures of aromatic and aliphatic esters of diols as plasticizers

A portion of the repeating units in polyesters useful as plasticizers for rigid organic polymers are derived from diethylene glycol and at least one dicarboxylic acid. The percentage of these repeating units that can be present in polyesters that are compatible with the organic polymer into which they are incorporated is inversely proportional to the weight average molecular weight of the polyester.
