由於冠狀醚可以和許多金屬離子以選擇性的產生錯合反應，尤其與鹼金屬離子，效果特別顯著。冠狀醚不只可以增加金屬鹽類（MX）在有機溶劑中的溶解度，進而促使金鹽之陰離子（X-）自由且活化；所以能催化陰離子（X-）所參與的有機反應。在本研究中，利用此優越旳特性，將各種冠狀醚做為相轉移催化劑，用於催化聚石風高分子（sulfones）縮合聚合反應及苯乙烯與丙烯月青陰離子高分子聚合反應。
本研究所探討影響高分子催化聚合反應的因素包括：冠狀醚的效應，起始劑的濃度、溶劑及溫度等聚合物的特性如分子量、黏度、IR及NMR光譜亦加探討，若沒有冠狀醚的參與，所得的聚合產物之產率低且分子量小，然而在冠狀醚的加入後，則產率及分子量均大輻提高，以醯胺鈉做為起始劑，其反應性比氫氧化鈉大很多，在用醯胺鈉為起始劑時，各種冠狀醚的催化能力依序為：(15冠5)15crown5>Benzo15crown5>18crown6>DC18C6>DB18C6>12C4在聚楓樹脂的合成，醯胺鈉取代氫氧化鈉的作用，可使反應進行時之中間產物，免於水解的困擾，即所產生的雙酚柄鹽因不會水解而安定且可順利的與4, 4'二氯二苯基楓聚合，比傳統的聚合方法簡化許多。
在冠狀醚的催化之下，聚楓樹脂分子量，分佈在20,000左右，聚丙烯月青分子量分佈則高達500,000萬，聚苯乙烯分子量分佈則較廣則從數百到五萬到二十幾萬都有，這些聚合物其分子量均與冠狀醚的濃度有關，一般冠狀醚的用量太多時分子量反而變小，此將作為推廣應用時良好依據。另外與許多傳統反應方法相較之下，本研究實驗裝置聚合工程上的大量生產將指日可待。

It's has been demonstrated that crown ethers are able to form quite stable complexes with many metal ions especially alkali metal ions. Crown ethers not only can increase the solubility of metal salts (MX) in organic solvent but also can promate the activation of the anions (X-) of alkali metal salts (MX). IN this study crown ethers were successfully applied as phase-transfer-catalysts for anionic polymerizations of bisphenol A/sulfone and vinyl monomers such as acrylonitrile and styrene.
Effects of crown erhers, concentrations of initiators (NaNH2, NaOH, KOH ), solvents, and temperature on polymerization were investrgated, In addition, the moleculat weight, viscosity, IR, and NMR spetra of polymers were studied. Without crown ethers as catalysts, only low yield and low molecular weight polymers were produced, whereas the addition of crown ethers resulted in increase of the yield and molecular weight remarkly. The catalytic abbilities of crown ethers seem to be in the order of : 15 crown 5>B15 crown 5>18C6>DC18C6>DB18C6>12C4. NaNH2 not only can be used as a quite good initiator but also can get rid of the problems of hydrolysis in copolymeriation bisphenol A and 4, 4'-dichloro diphenyl sulfone. The reaction procedures for polymerization of bisphenol A /sulfone, acrylonitrile, and styrene are quite simple and useful, while critical condition were required in the traditional methods for polymerization of bisphenol A/sulfone.
Crown ethers have been demonstrated as quite efficient phase-tranrfer-catalysts and maybe to be applied in industrial mass production for these useful polymers in the future.
