A general method for synthesizing active ethers (with complete etherification) synthesized from vinyl alkyl ether and low molecular weight phenol is investigated and the optimum synthesis conditions are proposed in this paper. Established a series of parameters between phenol and imaging, e.g., hydroxy equivalent(NOH), critical alkaline aqueous insoluble hydroxy equivalent, critical alkaline aqueous soluble hydroxy equivalent and MP/A value interpreted as ratio of dissolution inhibition to dissolution acceleration. Established alkaline solubilities of phenol (ASTW) based on various imaging requirements: highly alkaline soluble, alkaline soluble, slightly alkaline soluble and alkaline insoluble. Measured or calculated parameters of active ether, i.e. average ether equivalent, calibrated average ether equivalent related to molecular weight, ME/AE value and DL (ration of ME/AE to MP/A). Proposed several empirical formulae and molecular design rules of active ether for photo/thermal imaging based on the above parameters as well as author's experiences in photo/thermal imaging. © Copyright.
