Polyurethane/methyl methacrylate copolymer interpenetrating polymer networks with opposite charge groups (ionomer IPNs) were synthesized from NPU and PMMA-MAA
NPU was prepared from poly(oxyethylene) glycol
2
4-tolylene diisocyanate and bis (2-hydroxy ethylene) butylamine
PMMA-MAA was prepared by copolymerization of methyl methacrylate and methacrylic acid. The results of kinetics study showed that the formation rate of ionomer IPNs was slower than that of usual IPNs
the polymerization rate of two networks restrained one another
and increased with concentration of ionic bond. However
the poly-merization mechanisms of two networks were not affected.
