A Fortran IV program for determining copolymerization reactivity ratios is proposed. The program is based on the curve-fitting method and has the advantage of delivering values free of personal judgement. To check its validity the system benzylacrylate (BeA)/methylmethacrylate (MMA) was investigated

Rezctivelnon-reactive
branching ratios and the energy distribution in both branches were computed using arzaiytical classical mechanics for an idealized collinear collision. The trajectory generated branching ratios are compared with the predictions of 3x1 information theoretic approach assuming only knowledge of the products state distribution. Over a wide range of variations in energy distribution in the reactants, vibrational energy spacings and rhe major topography of the potential energy surface it is found that the information theoretic branching ratio is invariably in qualitative accord with the direct computation.
