Resumen:
olymer beads of ethylene glycol dimethacrylate and 2-hydroxyethyl methacrylate [poly(EGDMA-co-
HEMA)] were synthesized by suspension polymerization using different EGDMA contents and stirring
speeds. The matrix pore system and the degree of crosslinking are evaluated mainly from the degree of
swelling in water, and a mathematical model to describe the network morphology is proposed. The
distribution of water into the network was determined from evaporation kinetics of swollen samples,
then parameters such as porosity and increase of pore and network volumes were calculated. Networks
with a highly stable system of pores were formed when the EGDMA content is higher than 10 mol% for
stirring speeds higher than 300 rpm.
