2-hydroxyethyl methacrylate initiator concentration effect

Figure 9. Effect of the initial reactant ratio on the viscosity change during reaction between styrene-hydroxyethyl methacrylate copolymer (2.2 mole % HEM A) and hexamethylene diisocyanate in toluene at 80°C. Polymer concentration 0.134% (gram/dl.) [NCO]0 [OH]0 = 0.5, 1.1, 4.0, 18.4, 115, and 4000 for Curves IS, respectively... Figure 9.

Infrared spectroscopy is a useful tool to identify functional groups through vibrational frequencies in polymers to evaluate changes in structure This research was focused in graft copolymerization of Hydroxyethyl methacrylate (HEMA) onto chicken feathers fibers (CFF) and carboxymethyl cellulose (CMC), evaluating effect of reaction conditions (time reaction, monomer concentration, initiator concentrations) on grafting yield and probe presence of HEMA in copolymers by means Infrared Spectroscopy (IR). [Pg.248]
