Ethyl ethylene phosphate

Fig. 10 Relationship of percentage of dimer [62] to MEP in hydrolysis of M EP in 0.33 M NaOD. The equation for the curve is not given. The stated error in each point is 1.5% (e.g. (11.2 1.5) % dimer). [Reprinted with permission from Tetrahedron 43, Gorenstein et a/., Alkaline hydrolysis of methyl and ethyl ethylene phosphates .

In addition to in vitro mineralization to evaluate the hone bonding ability of a material, the study of cellular responses to materials intended for use at the bone interface is also important. Using ethyl ethylene phosphate-based polymer (EEP), Wang et al ° investigated cell behavior on a spin-coated P(LLA-Z)-EEP) scaffold. They found that osteoblast attachment and proliferation was significantly enhanced on the PEEP-modified PLEA surface. 

By inclusion of a proton source, such as H3PO4, water, or an alcohol, these oligomers can be made with hydroxyl functionality. Thus, a hydroxyl-terminated ethyl ethylene phosphate, Exolit OP 550, is made from triethyl phosphate, P2O5, phosphoric acid, water, and ethylene oxide. It has been introduced by Clariant as a reactive flame retardant for polyurethane foams (135).

Chew et al. (2005) demonstrated the utility of nanofibers elecirospun fiem copolymers of caprolactone and ethyl ethylene phosphate [P(CL-EEP)] in drug delivery. These were electrospun from 2-12% solutions in CH2CI2 and were loaded with low concentrations ( 1 x 10 " %) of recombinant human P-NGF stabilized in BSA carrier protein. Nanofibers were spun as aligned mats using a rotating drum collector and their BSA-NGF release characteristics were studied over a three-month period. The released protein was shown to be bioactive (using a neurite outgrowth assay on PC-12 cells).

Also, the novel enzymatic ring-opening copolymerization of ethyl ethylene phosphate (EEP) and TMC was performed in bulk at 100 °C using PPL or C. rugosa lipase to yield random copolymers having molecular weights ranging from 3200 to... 

Figure 3 shows the first-order kinetic plots for the polymerization of monomer ethyl ethylene phosphate (EEP) at different temperatures, where [A ]o/ [M], and [A ]eq are concentrations of EEP at time 0, time t, and equilibrium. The linearity of these plots demonstrated that the EEP consumption is in first order with reaction time and can be described by...
