Ethylene diacrylate

Acryloyl chloride (0.2 mol) in dry benzene (60 ml) was added over 0.5 hour with mechanical stirring to pentane-1,5-diol (0.1 mol), triethylamine (0.2 mol) and pyrogallol (0.1 g) in dry benzene (100 ml). Further dry benzene (ca 100 ml) was added followed by triethylamine (10 ml), and the mixture stirred at 50°C for 0.5 hour. The triethylamine hydrochloride was fii-tered off and the solvent removed In vacuo to leave a yellow oil which was distilled in the presence of a trace of p-methoxyphenol, excluding light, to give 1,5-pen tarn ethylene diacrylate (12.9g 61% BP90°to95°C/0,01 mm Hg),...

Reaction of ethylene diacrylate, which is commercially available, and subsequent reduction with lithium aluminum hydride gives endo-5-norbomene-2-methanol with 78 % ee. Although it is not clear why selectivity is increased by the link between di-enophiles, similar effects are expected for other asymmetric reactions (Eq. 38). 

When ethylene diacrylate is used as a cross-linking agent several authors (Bishop et al. 1967 Peacock and Dingman 1967) advocate the use of up to 3 times higher ratio of cross-linker to acrylamide than normally used in the case of N,N -methylenebisacrylamide for comparable separations. 

Efficient toughening by the rubber modifier can be obtained, as discussed earlier, only if the RLP is capable of sufficient grafting to the epoxy matrix. Theoretically, the optimal linear rubber chain should possess two terminal reactive groups. Since this configuration could not be synthesized in dilute solution polymerization, a branched copolymer of nBA and ethylene dlacry-late (EDA), structure I, with a potentially higher functionality, was studied. Ethylene diacrylate is used primarily as a cross-... 

Sulfur, or the so-called coagents (Loan, 1963 Lenas, 1964), can be used to suppress scission. Examples of coagents are m-phenylenebismaleimide, high-1,2 (high-vinyl)polybutadiene, triallyl cyanurate, diallyl phthalate, and ethylene diacrylate. Their mechanism of action may be as follows ... 

Depending upon polsrmerization concentration, difunctional acrylic compounds (eg, ethylene diacrylate) may give polymers that are hyperbranched, hyper-cross-linked, or both.

Complex-forming POE/PAA interpenetrating polymer networks have been prepared by matrix polymerization of acrylic acid and ethylene diacrylate (a crosslinking agent) with a precrosslinked POE that was formed from hydroxyl-terminated POE and 2-isocyanatoethyl-2,6-diisocyanatohexanoate (131). At low degrees of POE crosslinking, dynamic mechanical properties in-...
