Pentadiene can be used to model ferf-butylbutadiene in Reaction (5.1). The carbonyl group affects the dienophile much more than the methyl, which can then be neglected. The ester function can also be replaced by an aldehyde (verify that ethyl 2-methacrylate can be simulated by either methyl 2-methacrylate, 2-methylacrolein, methyl acrylate or acrolein). In each case, the first-formed bond will link the atom having the highest HOMO coefficient in the diene to the atom having the highest LUMO coefficient in the dienophile. 

ETHYL-1-2-METHACRYLATE or ETHYL-2-METHACRYLATE (97-63-2) Forms explosive mixture with air (flash point 68°F/20°C). Able to form unstable peroxides can polymerize unless inhibited. Violent reaction with strong oxidizers, benzoyl peroxide, or other polymerization initiators. Elevated temperatures, light, contamination can cause spontaneous, explosive polymerization. Incompatible with caustics, nitrates, strong acids, amines, alkanolamines, peroxides. Flow or agitation of substance may generate electrostatic charges due to low conductivity. The uninhibited monomer vapor may block vents and confined spaces by forming a solid polymer material.

Poly(ethyl methacrylate) (PEMA) yields truly compatible blends with poly(vinyl acetate) up to 20% PEMA concentration (133). Synergistic improvement in material properties was observed. Poly(ethylene oxide) forms compatible homogeneous blends with poly(vinyl acetate) (134). The T of the blends and the crystaUizabiUty of the PEO depend on the composition. The miscibility window of poly(vinyl acetate) and its copolymers with alkyl acrylates can be broadened through the incorporation of acryUc acid as a third component (135). A description of compatible and incompatible blends of poly(vinyl acetate) and other copolymers has been compiled (136). Blends of poly(vinyl acetate) copolymers with urethanes can provide improved heat resistance to the product providing reduced creep rates in adhesives used for vinyl laminating (137). 

The alcohol swells the poly (ethyl methacrylate) beads, rapidly promoting diffusion of the plasticizer into the polymer. As a result of the polymer-chain entanglement, a gel is formed. The conditioner is applied to the denture and provides a cushioning effect alcohol and plasticizer are slowly leached out, and the material becomes rigid. To ensure resiliency, the conditioner must be replaced after a few days. Some materials exhibit high flow over a short period compared with others with low initial flow the latter remain active longer. 

Ethyl methacrylate [97-63-2] M 114.2, b 59 /100mm, d 0.915, n 1.515. Washed successively with 5% aqueous NaN02, 5% NaHS03, 5% NaOH, then water. Dried with MgS04, added 0.2% (w/w) of phenyl-6-naphthylamine, and distd through a short Vigreux column [Schultz J Am Chem Soc 80 1854 7958]. 

Hydroxy-containing polymers such as poly(methyl-methacrylate-co-hydroxyethyl methacrylate) [65,66] or secondary cellulose acetate [67,68] were used for this purpose. Vanadium (V) 8-hydroxy quinoline-hydroxy-ethyl methacrylate adduct, prepared by condensation of the latter with a VOQ2OH complex, is polymerized to...
