Knowledge of aminomethyl polystyrene resin

Macroporous aminomethyl polystyrene resin differs from the gel aminomethyl resin by the presence of permanent pores in the polymer, even in the dry form. Transport of molecules to the reactive sites in a macroporous polymer is much faster than in nonmacroporous polymer of the same macroparticle size and degree of the cross-linking because most of transport occurs through liquid-filled pores rather than through the cross-linked matrix. 
This resin will be useful if you have a specific linker that you want to load yourself on the resin. If you have a need for a resin that is not offered at this time, please discuss with your sales representative as we also do custom development for our customers.
So macroporous aminomethyl polystyrene resin distinctively benefits the solid phase synthesis. It is also useful for applications where you wish to have a molecule linked permanently on the  resin.
