A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure: M--Z--O--C(R.sup.1 R.sup.2 R.sup.3) wherein M is an alkali metal; Z is a branched or straight chain hydrocarbon group which contains 3-25 carbon atoms, optionally containing aryl or substituted aryl groups; and R.sup.1, R.sup.2, and R.sup.3 are independently selected from hydrogen, alkyl, substituted alkyl, aryl or substituted aryl groups, and their employment as initiators in the anionic polymerization of olefin containing monomers in an inert, hydrocarbon solvent comprising reacting an omega-protected-1-haloalkyl with lithium metal dispersion having a particle size between 10 and 300 millimicrons in size, at a temperature between 35.degree. and 130.degree. C. in an alkane solvent containing 5 to 10 carbon atoms.
一种制备单官能醚引发剂的烃溶液的方法,其具有以下一般结构:M--Z--O--C(R.sup.1 R.sup.2 R.sup.3),其中M是碱金属;Z是一个含有3-25个碳原子的支链或直链烃基,可选地含有芳基或取代芳基;R.sup.1、R.sup.2和R.sup.3分别从氢、烷基、取代烷基、芳基或取代芳基中独立选择,并将它们作为引发剂在惰性、烃溶剂中的烯烃单体的阴离子聚合中使用,包括在含有粒径在10至300毫微米之间的锂金属分散体的ω-保护-1-卤代烷基与在35°C至130°C温度范围内的烷烃溶剂中的5至10个碳原子反应。
