A　stable　poly(META-co-PETA)　monolith　was　fabricated　and　employed　for　hydrophilic　interaction　(HI)　and　dynamically-modified　reversed-phase　(RP)　electrochromatography.　Detailed　effects　on　the　column　characteristics　including　the　permeability,　swelling　propensity　factor,　retention　factor,　EOF　and　column　efficiency　were　investigated.　Studies　on　the　column　stability　and　heat　dissipation　were　also　implemented.　The　interrupt　problem　caused　by　joule　heating　was　eliminated　and　the　satisfactory　characteristics　in　terms　of　the　uniform　morphology,　good　reproducibility　and　multiple　retention　modes　were　gained.　Based　on　the　obtained　monolith,　versatile　separation　interactions　including　HI,　RP,　HI-strong　anion　exchange　(HI-SAX)　and　RP-SAX　were　evaluated　and　utilized　for　capillary　electrochromatography　(CEC).　Efficient　separations　of　phenols　and　nucleic　acid　bases　and　nucleosides　were　achieved　with　HI-CEC.　With　an　easy　dynamical　modification　of　sodium　dodecylsulfate　(SDS),　efficient　separations　of　alkyl　benzenes,　polycyclic　aromatic　hydrocarbons,　estrogens　and　basic　anilines　were　also　achieved　with　RP　or　RP-SAX.　It　presented　a　facile　polymer　monolith　for　hydrophilic　and　dynamically　SDS-modified　RP　modes　in　CEC.
