POLYETHYLENE GLYCOL COMPOUNDS AND PROCESS FOR MAKING
摘要
<p>A substituted polyethylene glycol compound and process for making. The compound has the formula RO(C<SUB>2</SUB>H<SUB>4</SUB>O)<SUB>n</SUB>H wherein R represents a C<SUB>1-7 </SUB>hydrocarbon group and n represents the average number of moles of C<SUB>2</SUB>H<SUB>4</SUB>O groups, ranging from 500 to 2000. The compound has a ratio of weight average molecular weight to a number average molecular weight in the range of from 1 to 1.1. The compound contains less than ten weight percent polyethylene glycol. The gist of the process is the use of an aprotic polar solvent. When the aprotic polar solvent is a polyether solvent, then the n value of the compound ranges from 100 to 2000.</p>
