Reactivity ratios have been determined for the anionic copolymerization of ethylene oxide and propylene oxide in bulk over the temperature range 0-80°C. The ratios were obtained by two methods, the first using the variation of copolymer composition with monomer feed composition according to the May~
## Abstract Neodymium tris(2‐ethylhexylphosphonate)‐triisobutylaluminum‐water system was investigated as a catalyst in ethylene oxide and propylene oxide copolymerization. Random copolymers of ethylene oxide and propylene oxide were obtained with high yield and high molecular weight in a short reac
Abstract\_(:opolymers of ethylene oxide and propylene oxide were prepared to low conversion at temperatures in the range &8o"C, and the number of unsaturated end groups relative to copolymerised oxypropylene groups in each sample was determined by NMR spectroscopy. The data were analysed to yield va
A~traet--Reactivity ratios have been determined for the anionic copolymerization of ethylene oxide and butylene oxide in bulk at temperatures of 40 and 60 °. The ratios were obtained from the variation with feed composition of: (i) copolymer composition; and (ii) triad sequence probabilities. Finite
