Ethylene glycol dimethacrylate crosslinking agent

The effect of the solvent on the characteristics and release of carbamazepine MIP nanospheres and the syntheses and characterization of MIPs for the release of bromh-exine has also been reported [232,233], In the latter case, the MIPs were prepared using methacrylic add monomers ethylene glycol dimethacrylate crosslinking agent. 

Addition of typical crosslinking agents,such as 20% diallyl phthalate, 10% ethylene glycol dimethacrylate, 1% maleic anhydride or 1% itaconic anhydride, to the isobutyl 2-cyanoacrylate so that after curing a more rigid,insoluble, hydrolytically stable polymeric adhesive might be formed,does not increase the strength of the dentin-poly(methyl methacrylate) joint. Perhaps the cross-linked adhesive possesses decreased resistance to the thermal shock encountered by the test specimens. 

The typical mole ratio of atrazine, methacrylic acid, and ethylene glycol dimethacrylate in chloroform is 1 3-5 25-30. Although the adduct is formed from one atrazine and two methacrylic acids (Fig. 6.2), the atrazine/methacrylic acid ratio in the mixtures is usually kept around 4 to move the equilibrium toward the formation of these hydrogen-bonding adducts. The mole ratio of crosslinking agent to the template is in general 20-30. 

Eldred [1974] electron-irradiated EPR and EPDM in air, in the presence or absence of the following crosslinking agents ethylene glycol dimethacrylate, EDMA, 1,4-hexadiene, HD,... 

Figure 5. Dependence of the specificity of the polymers on the kind and the amount of crosslinking. Polymers imprinted with were prepared with varying amount of the crosslinking agents ethylene glycol dimethacrylate, butanediol dimethacrylate, and p-divi-nylbenzene. After splitting off the templates the separation factor a for the optical resolution of phenyl-a-D,L-mannoside in the batch procedure was determined.

Monomer 268 was also copolymerized with hydroxyethyl methacrylate and ethylene glycol dimethacrylate as crosslinking agent in a 1/7/2 ratio to lead to the new polymer-supported alkaloid 274 (Scheme 112) [171]. This one was insoluble in all solvents and swelled very well in protic polar solvents. The catalytic activity of chiral polymer 274 was... 

In order to improve the enantioselectivity in the AD of aliphatic alkenes, the two dihydroquinidine-derived polymers 275 and 276 were prepared by radical copolymerization of the corresponding monomers with hydroxyethyl methacrylate and ethylene glycol dimethacrylate as crosslinking agent (Scheme 112) [172], These two polymers 275 and 276 exhibited enhanced enantioselectivities (88 and 86% vs 75% with polymer 274) for the dihydroxylation of two aliphatic alkenes, 1-decene and 5-decene compared to those observed... 

A poly(L-lactic acid) was fed to a double screw kneader at 200°C. To this, ethylene glycol dimethacrylate as a crosslinking agent and dibutyl peroxide as a radical pol5nnerization initiator were added. Pellets were formed from this mixture. 

Alpha-tocopherol and 5-fluorouradl imprinted polyers reported by Puod et al. were prepared using common fimdional monomers, i.e., methacrylic acid and ethylene glycol dimethacrylate and 2,2 -azoisobutyronitrile as the crosslinking and initiator agents.
