    • A method of quenching which comprises the steps of (a) immersing a metal heated to an elevated temperature in a quenchant composition comprising an aqueous-solution of a sufficiently hydrophilic water-soluble or water-dispersible organic polymer of the formula:Y[AR].sub.xto provide a solution containing 15.0 weight percent of polymer and a balance of water with a Drag Out Value of less than about 40, preferably less than about 35 and most preferably less than about 25 under Standard Conditions; whereinY is the residue of an active hydrogen-containing organic copound following active hydrogen removal;x is an integer having a value of at least 1; wherein for values of x greater than 1 each AR segment of the polymer is the same or different;A is a random or block polyoxyalkylene residue having units derived from ethylene oxide and at least one other lower alkylene oxide having 3 or 4 carbon atoms; andR is hydrogen or an hydrolytically stable organic moiety;wherein for values of x greater than 1 each AR segment of the polymer is the same or different; with the proviso that R is only hydrogen or an organic moiety less hydrophobic than propane either when x is 1 and Y is at least as hydrophobic as hexane or when x is greater than 1 and at least one other R, individually or in combination is sufficiently hydrophobic to depress the cloud point of a 10% by weight aqueous solution of the corresponding Y[AR].sub.x, wherein R is hydrogen, by 10.degree. F.; and (b) removing the metal from the quenchant when a desired low temperature is reached.
    • 一种淬火方法,其包括以下步骤:(a)将被加热到高温的金属浸入包含下式的足够亲水的水溶性或水分散性有机聚合物的水溶液的骤冷剂组合物中:Y [AR] x以提供含有15.0重量%的聚合物和余量的水的溶液,在标准条件下的Drag Out值小于约40,优选小于约35,最优选小于约25; 其中Y是活性氢去除后的含活性氢有机物的残基; x是至少为1的整数; 其中对于x大于1的值,聚合物的每个AR链段相同或不同; A是具有衍生自环氧乙烷和至少一种具有3或4个碳原子的其它低级环氧烷的单元的无规或嵌段聚氧化烯残基; 并且R是氢或水解稳定的有机部分; 其中对于x大于1的值,聚合物的每个AR链段相同或不同; 条件是当x为1且Y至少与己烷一样疏水时或当x大于1时,R仅为氢或有机部分疏水性较小的丙烷,而x大于1,并且至少一个其它R单独或组合足够 将10重量%相对应的Y [AR] x(其中R为氢)的10重量%水溶液的浊点降低10℃。 和(b)当达到所需的低温时,从淬火剂中除去金属。
