Room‐temperature kinetics of castor‐oil‐based polyurethane/poly(2‐hydroxyethyl methacrylate) interpenetrating polymer networks

Abstract

SYNOPSISThe kinetics aspects of the formation of castor-oil-based polyurethane/poly (2-hydroxyethyl methacrylate) interpenetrating polymer networks ( IPNs) were studied. The effect of parameters such as the polyurethane content, the activator, and acrylic cross-linker on the kinetics of formation of IPN networks was examined at room temperature. The formation of the individual networks, polyurethane, poly (2-hydroxethyl methacrylate), and their IPNs, was studied by measuring the decrease of absorbance of characteristic absorption peak of each system using IR spectroscopy.

Evaluation of poly(hydroxyethyl methacrylate) imaging chemistries for micropatterning applications

“…[35][36][37][38][39][40] Several fundamental studies on protein interactions with PHEMA and its copolymers have also been published. 41,42 Well established patterning processes would be of great interest in these areas since they could eliminate the need for crosslinkers and unreacted monomers in the material composition 43,44 and offer new routes for nanotechnology applications. In addition, the well-established biocompatibility of HEMA homopolymers or copolymers could be exploited in the development of new materials and processes suitable for use in specific applications, e.g.…”
