Notizen:
Copolymers of allyl glycidyl ether (AGE) with acrylonitrile (AN) have been prepared by bulk polymerization of their monomers with gamma rays. Copolymers thus obtained were characterized by Fourier transform infrared (FTIR), and ultraviolet (UV) spectroscopic techniques. The composition of the copolymers is determined indirectly by FTIR, UV, and directly by elemental analysis. The results obtained by different methods are compared. The reactivity ratios of monomer pairs (AGE + AN) which copolymerized heterogeneously were calculated by using different methods of determination. Among the three experimental methods used for the analysis of compositions and two theoretical methods of computations, the elemental analysis technique and the application of nonlinear least-squares method gave the most reliable reactivity ratios. These are found to be 1.86 and 0.21 for acrylonitrile and allyl glycidyl ether, respectively. © 1996 John Wiley & Sons, Inc.
