Abstract
New macroporous polymer rods were prepared by free-radical crosslinking
copolymerization from N-acryloyl-tris(hydroxymethyl)aminomethane and N,N'-
methylenebisacrylamide as a crosslinking agent with different porogenic mixtures
and with azobisisobutyronitrile as an initiator. The porous properties of these materials
were controlled through changes in the proportions of the porogenic mixture, the
polymerization temperature, or the concentration of the crosslinking agent. Pore size
distribution profiles that shifted toward a larger pore size were obtained in the following
cases: when the percentage of the coporogen was increased, when the copolymerization
reactions were carried out at a low temperature (55 °C), and when the
crosslinking concentration was reduced. Alternatively, a porogenic mixture formed
from dimethyl sulfoxide and a 1:1 combination of tetradecanol and poly(ethylene glycol)
6000 as coporogens yielded a polymer rod with a high porosity and pore size.
These hydrophilic materials are promising as base supports for different chromatographic
processes and as throughput bioreactors.
