Porous copolymers of methacrylic acid with N-(2-hydroxypropyl) methacrylamide and (2-hydroxyethyl) methacrylate. Preparation, swelling and morphology

Porous copolymers of methacrylic acid with N-(2-hydroxypropyl) methacrylamide or (2-hydroxyethyl) methacrylate were prepared using 1,3,5-triacryloylhexahydrotriazine as the crosslinking agent. The copolymers were characterized by their swelling, bulk weight, and morphologically by scanning electron microscopy. Data thus obtained were used in the interpretation of the formation of different porous morphology, differing in the size and ordering of globules.
