IMPROVEMENTS IN OR RELATING TO PLASTICISER ESTERS

摘要

Terephthalic acid di-alkyl esters in which the alkyl groups of the ester are obtained from branched C5 to C13 alcohols or mixtures of mixtures of C5 to C13 linear and branched alcohols in which less than 50 mole % of the alcohols are linear alcohols and the branched chain alkyl groups of such alcohols contain methyl groups and have an average of more than 7 carbon atoms and are free of ethyl groups. The di-esters are particularly useful as plasticizers and particularly plasticizers for polyvinyl chloride.
