Ananysis of tetrapolymer of allylamine

Does anyone have any advice regarding HPLC analysis of polymers of allylamine (hydrocarbon chains not peptide chains)? There is significant cross linking involved which prevents this from being completly soluble. Suggestions would be appreicated.

Similar polymers have been analyzed using glycidylmethacrylate packings, such as the Ultrahydrogel column series. A few polymers are listed in my book "HPLC Columns": polyvinylamine in water with 0.8 M Na NO3, polyepiamine with water and 0.1M triethylamine, etc.

"HPLC analysis of polymers of allylamine"
What does this question mean? You want a MW distribution, quantitate this stuff in something else, look for oligomer, branching, cross link density, impurities, monomer,extractables, catalyst?
