"Dowex 50" is a type of ion-exchange resin, called a strongly acidic cation exchanger, used for ion-exchange chromatography. It is useful for swapping a metal cation for a proton (eg. Na+ for H+) or one metal cation for another (eg. K+ for Na+). This can be an important way for purifying amino acids, carboxylate salts or removing unwanted metal ions from water solutions.

Most resins do not stick to wax paper
Arcyrilic acid is a pungent organic acid that can be polymerized to make the synthetic resins.
Dowex 50 is a wellknown ion exchanger.
In dowex 2 the active part is -N(CH3)2(C2H4OH)(+) (all three groups linked with nitrogen atom, of course - I don't know if this formula is clear) and dowex 50 is simply -SO3(-)
lon Exchange Resins
A method for blowing synthetic resins as a fuel into a furnace comprising: processing synthetic resins consisting essentially of film shaped synthetic resins by melting or semi-melting the synthetic resins by heat to produce granular synthetic resins having a bulk density of at least 0.3 and angle of repose of up to 40 degrees; pneumatically feeding the granular synthetic resins from the processing; and blowing the pneumatically fed granular synthetic resins into a furnac

Epoxy resins are advanced thermosetting resins used in FRP composites. Epoxy equivalent of an epoxy sample is determined by a standard titration method [6] using hydrogen bromide solution in acetic acid.
