When used with methyl methacrylate, it leads to gel point at relatively low concentrations because of the nearly equivalent reactivities of all the double bonds involved. It is used as a monomer to prepare hydroxyapatite/poly methyl methacrylate composites. EGDMA can be used in free radical copolymer crosslinking reactions.
A large family of acrylate-like polymers are derived from methyl methacrylate and many related esters, especially polymethyl methacrylate. A second large family of acrylate-like polymers are derived from ethyl cyanoacrylate, which gives rise to cyanoacrylates.
Poly(ethyl acrylate) (PEA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 2 CH 3) n. It is a synthetic acrylate polymer derived from ethyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from ethyl acrylate and other monomers.
In terms of the acute toxicity of methyl methacrylate, the LD 50 is 7–10 g/kg (oral, rat). It is an irritant to the eyes and can cause redness and pain. [16] [17] Irritation of the skin, eye, and nasal cavity has been observed in rodents and rabbits exposed to relatively high concentrations of methyl methacrylate. Methyl methacrylate is a ...
Poly(ethyl methacrylate) (PEMA) is a hydrophobic synthetic acrylate polymer. It has properties similar to the more common PMMA, however it produces less heat during polymerization, has a lower modulus of elasticity and has an overall softer texture. [7] It may be vulcanized using lead oxide as a catalyst [8] and it can be softened using ethanol.
Ethyl acrylate reacts with amines catalyzed by Lewis acids in a Michael addition to β-alanine derivatives in high yields: [13]. The nucleophilic addition at ethyl acrylate as an α,β-unsaturated carbonyl compound is a frequent strategy in the synthesis of pharmaceutical intermediates.
