Dibenzyl sebacate

Diesters. Many of the diester derivatives are commercially important. The diesters are important plasticizers, polymer intermediates, and synthetic lubricants. The diesters of azelaic and sebacic acids are useflil as monomeric plasticizing agents these perform weU at low temperatures and are less water-soluble and less volatile than are diesters of adipic acid. Azelate diesters, eg, di- -hexyl, di(2-ethylhexyl), and dibutyl, are useflil plasticizing agents for poly(vinyl chloride), synthetic mbbers, nitroceUulose, and other derivatized ceUuloses (104). The di-hexyl azelates and dibutyl sebacate are sanctioned by the U.S. Food and Dmg Administration for use in poly(vinyl chloride) films and in other plastics with direct contact to food. The di(2-ethylhexyl) and dibenzyl sebacates are also valuable plasticizers. Monomeric plasticizers have also been prepared from other diacids, notably dodecanedioic, brassyflc, and 8-eth5lhexadecanedioic (88), but these have not enjoyed the commercialization of the sebacic and azelaic diesters. 

Although bisphenol A polycarbonate is plasticized by a 30% concentration of dibutyl phthalate or dibenzyl sebacate (Table III), as has been reported (6, 7), a higher concentration is required for effectively plasticizing the polycarbonates of bisphenols I and II (Tables I and II). Perhaps the reason for this is the appreciably lower mobility of polymer chains containing bulky, three-dimensional, polycyclic structures than chains of the bisphenol A polycarbonate. So even though a plasticizer may weaken the secondary attraction forces between polymer chains,...

Plasticizers. Softeners are sometimes employed with nitrile rubbers to improve tack and adhesive properties. They are added to high nitrile content rubbers to aid processability. Conunonly employed in cement applications are esters (e.g., dibutyl phthalate, dioctyl phthalate, tricresyl phosphate, tributoxy ethyl phosphate, dibenzyl sebacate), ester gums.
