Abstract
In this study, new hydrogels in rod shape were prepared from N-acryloyl-
TRIS(hydroxymethyl)aminomethane (NAT) using ethylene glycol dimethacrylate
(EGDMA) or N,N'methylenebisacrylamide (BIS) as crosslinking agent,
dimethylformamide (DMF) as solvent and benzoyl peroxide (BPO) as initiator. In
most cases, 2-hydroxyethyl methacrylate (HEMA), acrylamide (Aam) or acrylic acid
(Aac) were used as co-monomers. The polymeric matrices obtained by free radical
polymerization exhibited different properties by changing crosslinker, crosslinker
concentration, co-monomer and initial NAT/co-monomer mole ratio. Besides,
hydrogels from HEMA, Aam and Aac with BIS in absence of NAT were prepared
under the same experimental reaction conditions in order to compare the properties of
these products with those synthesized from NAT and the respective co-monomers.
Some of the final products were selected to perform urea release assays, conducted
through swelling-controlled release. Urea was chosen as "model" plant fertilizer agent.
