摘要
本文提供了低分子量酚类化合物与乙烯基烷基醚合成醚化率百分之百的高酸解活性醚化物(以下简称活性醚化物)的一般合成方法,并对其合成条件的优选进行了讨论.建立了原料酚类化合物与成像性能密切相关的参数,如羟当量,临界碱水不可溶羟当量,临界碱水可溶羟当量,表征原料酚类化合物阻溶、促溶能力比的M_P/A值,按照成像要求所设定的碱水易溶、碱水可溶、碱水微溶、碱水不溶(难溶)的AS_(TW)参数.测定或推算出活性醚化物的平均醚当量、与分子量相关的校正醚当量、活性醚化物的M_E/A_E值以及M_E/A_E值与M_P/A值的比值(即DL值)等多项参数.围绕上述参数的建立,提出了一些经验计算公式,根据所建立的参数值以及多年来从事光/热成像实验的实践,提出了光/热成像用活性醚化物分子设计的有关规则.
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 a/kaline soluble and alkaline insoluble. Measured or calculated parameters of active ether, i.e. average ether equivalent, calibrat- ed average ether equivalent related to molecular weight, ME/As 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.
