Azelaic, sebacic, dodecanedioic, and brassyhc acids may be used in copolyetheresteramides (111). Two patents describe additional apphcations for the C-9—C-40 diacids for the preparation of polyester carbonates (112), and the copolymerization of epoxides and carbon dioxide by reaction of either glutaric or adipic acids with zinc oxide (113). 

The enzymatic synthesis of polyesters from activated diesters was achieved under mild reaction conditions. The polymerization of bis(2,2,2-trichloroethyl) glutarate and 1,4-butanediol proceeded in the presence of PPL at room temperature in diethyl ether to produce the polyesters with molecular weight of 8.2 x 10. Vacuum was applied to shift the equilibrium forward by removal of the activated alcohol formed, leading to the production of high molecular weight polyesters. The polycondensation of bis(2,2,2-trifluoroethyl) sebacate and aliphatic diols took place using lipases BC, CR, MM, and PPL as catalyst in diphenyl ether. Under the...

Various other processes not discussed here lead to mamrfacture of acids required for production of plasticizers. As previously mentioned, availability and price of acid rrray predetermine price and thus the likelihood of a plasticizer s itse. Acids are used not orrly in their pure forms but also in form of rrrixtures. For example DBE intermediates manrrfac-tured by DuPont are refined dimethyl esters of adipic, glutaric, and succinic acid are rrrix-tures for plasticizer synthesis.There are six mixtures of different composition which may be used for the production of polyester and diester plasticizers. Diester plasticizers are produced by transesterification according to the following equation ... 

The recent developments in Upase catalyzed synthesis of polyesters have been reviewed (61). A series of diacids, such as succinic add, glutaric acid, adipic acid, and sebacic acid and diols, such as 1,4-but-anediol, 1,6-hexanediol, and 1,8-octanediol have been pol5merized in solution and in bulk using lipase as a catalyst (62,63). 

Dimethyl glutarate (DMG) m A liquid chemical intermediate, a source of dicarboxylic acid, used in making plasticizers, polyester resins, synthetic fibers, films, adhesives, and solvents. 

Polymeric plasticisers such as polypropylene adipate, azelate, glutarate and sebacate (or mixtures of these substances) are much less volatile than ordinary low molecular weight plasticisers. They are not easily extracted, and they weather well, but they cost more than phthalates and are not as easily processed, being mostly high viscosity substances. They are often blended with phthalates as a compromise. The polyester adipates are the most widely used.
