doi:10.7517/j.issn.1674-0475.2010.01.37

Abstract

Abstract: 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(N_oh)>critical alkaline aqueous insoluble hydroxy equivalent,critical alkaline aqueous soluble hydroxy equivalent and M_P/A value interpreted as ratio of dissolution inhibition to dissolution acceleration.Established alkaline solubilities of phenol(AS_TW) 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,M_E/A_E value and DL(ration of M_E/A_E to M_P/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.

Key words: photo/thermal imaging, active ether, phenol, dissolution inhibitor/accelerator, molecular design
