The kinetics of polycondensation of sebacoyl chloride with α,ω-alkane dioles HO - (CH2)n - OH (5≤n≤10) in dioxane can be described by a second order law related to the functional groups. The rate constants at a given temperature have all the same value within the accuracy of the measurements. The mean values of the rate constants are k=0,63·10-3mol-1ls-1 (T=299,9 K),k=1,19·10-3mol-1ls-1 (T=312,9 K), and k=2,98·10-3mol-1l s-1 (T=331,8 K). Thus, these polycondensation reactions are independent of the chain length of the α,ω-dioles. The mean activation energy is EA=41 kJ mol-1 and the pre-exponential factor is A=8,5·10×3 mol-1ls-1.
