Cover Story: Alkyl acrylates (such as methyl, ethyl, and n-butyl acrylate) self-initiate polymer chains at high temperatures. The reaction mechanism and kinetics of the self-initiation had been studied theoretically using computational quantum chemistry. This work estimates the kinetic parameters of the n-butyl acrylate self-initiation apparent reaction from monomer-conversion measurements using a macroscopic-scale mechanistic model. The polymerization is carried out in n-heptane (solvent) at high temperatures without adding any conventional initiators. The estimated reaction kinetic parameters agree well with those predicted by computational quantum chemistry. View this paper

The error-in-variables-model (EVM) is the most statistically correct non-linear parameter estimation technique for reactivity ratio estimation. However, many polymer researchers are unaware of the advantages of EVM and therefore still choose to use r...
