Ethyl ethylene phosphate-based polymer

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. 

A series of compounded flame retardants, based on finally divided insoluble ammonium phosphate together with char-forming nitrogenous resins, has been developed for thermoplastics.23 These compounds are particularly useful as intumescent flame-retardant additives for polyolefins, ethylene-vinyl acetate, and urethane elastomers. The char-forming resin can be, for example, an ethyle-neurea-formaldehyde condensation polymer, a hydroxyethyl isocyanurate, or a piperazine-triazine resin. Commercial leach-resistant flame-retardant treatments for wood have also been developed based on a reaction product of phosphoric acid with urea-formaldehyde and dicyandiamide resins.
