✦ Synopsis

Alkyl alcohols have two AN (solvent acceptor number) values. One AN value for the alkyl alcohol is for intermolecular hydrogen bonded species such as (C==O:OH), and the other AN value for the alcohols is for the (ROH:OHR), species where the solute molecules are not hydrogen bonded with OH groups. The AN value for the latter species is similar to the AN values for dialkyl ethers. Steric factors of the solute and solvent are suggested to be the cause of the deviation from linearity of v(C.=O) vs. AN values of the solvents. Inductive and resonance effects are stated to be the cause of the v(c-0) frequency differences exhibited by the three esters included in this study.

A systematic study of the terpolymerization of butyl acrylate/methyl methacrylate/vinyl acetate (BA/MMA/VAc) was conducted. In this stage of the study, batch emulsion terpolymerizations were performed in a 5 L stainless steel pilot plant reactor. The experiments were designed using a Bayesian (optim
