On the kinetics of anionic copolymerization of ε‐caprolactam and ω‐dodecalactam

Abstract The kinetics of the anionic copolymerization of ε‐caprolactam and ω‐dodecalactam is discussed. The temperature regions of copolymerization with and without simultaneously occuring crystallization are determined. The enthalpy of copolymerization is calculated. The heat effect of each monomer was found to contribute additively to the overall heat of copolymerization. Based on the results obtained a method for determining the copolymer composition from the heat effects is proposed, considering the effects of crystallization.
