摘要：

A new linear method of calculation of monomer reactivity ratios is presented for copolymerizations up to very high conversion. It is a linear least-squares method involving several iterations. The basis of calculation is the differential copolymerization equation and the Kelen-Tudos (K-T) method. The principle and the calculation of computer-simulated data indicate that this new method can correct completely the systematic errors due to high conversion. Calculation using data in the literature shows that this method can be applied in any real systems. The comparison of K-T and extended K-T methods is also discussed.
