Diethylene glycol bis-allyl carbonate

Diethylene glycol bis (chloroformate) [106-75-2] is the starting material for diethylene glycol bis(allyl carbonate) [142-22-3] CR-39, or Nouryset 200, monomer, used in the manufacture of break-resistant optical lenses, which is obtained by the reaction with aHyl alcohol [107-18-6] (59). Alternatively, it can be obtained from aHyl chloroformate [2937-50-0] and diethylene glycol (60) (see Allylmonomers and polymers). 

The low refractive index monomer, diethylene glycol bis allyl carbonate, was prepared by Khandel et al. (4) and used in plastic ophthalmic lenses.

These discussions have been extended to the bulk polymerizations of diallyl adipate (DAA), diethylene glycol bis (allyl carbonate) (DEGBAC), and diallyl diphenate (DAD) accompanied by a greatly delayed gelation The monomer type, actual gel point (%), theoretical gel point (%) are, respectively, as follows DAA, 25.6, 3.6 DEGBAC, 23.0, 3.7 DAD, 29.2, 3.4.

Diethylene glycol bis(allyl carbonate) is used to form clear castings which have excellent thermal stability as well as scratch and abrasion resistance. The pol3uners and copolymers with methyl methacrylate are used in optical... 

Allyl alcohol undergoes reactions typical of saturated, aliphatic alcohols. Allyl compounds derived from allyl alcohol and used industrially, are widely manufactured by these reactions. For example, reactions of aUji alcohol with acid anhydrides, esters, and acid chlorides yield aUyl esters, such as diaUji phthalates and allyl methacrylate reaction with chloroformate yields carbonates, such as diethylene glycol bis(allyl carbonate) addition of allyl alcohol to epoxy groups yields products used to produce allyl glycidyl ether (33,34).

Only four allyl esters are of significant industrial importance as monomers for the production of homopolymers diethylene glycol bis(allyl carbonate), which, as CR-39, is widely used as a plastic spectacle lens material of exceptional clarity, scratch, abrasion, and impact resistance, and diallyl o- and m-phthalates, supplied commercially as soluble low-molecular-weight prepolymers. These prepolymers may be molded and subsequently cross-linked to give rigid plastic objects.
